HI 9812-0 • HI 9812-5 - Versatile Instruments for Water Conditioning

HI 9812 and HI 9812-5 are easy to use portable instruments for field measurement of pH, conductivity and TDS in water conditioning applications. These powerful instruments reduce your necessary tool set for field water quality analysis. HI 9812-0 measures pH from 0.0 to 14.0. This meter also checks conductivity and TDS from 0 to 1990 mg/L, ideal for the water conditioning field. Calibration has been simplified to one point for both pH and conductivity/TDS modes. Both HI 9812-0 and HI 9812-5 are equipped with Automatic Temperature Compensation to remove the effects of temperature on your conductivity and TDS measurements. In addition, the BEPS (Battery Error Prevention System) will alert the user when low batteries could affect the readings. HI 9812-0 uses HANNA instruments®’ 4-in-1 replaceable HI 1285-0 probe, while HI 9812-5 uses HI 1285-5. No probe changes are required when switching your measured parameter between pH, conductivity and TDS. The specially engineered pH electrode also features a fiber junction and gel electrolyte for faster response and reduced contamination. Finally, HI 9812-5 also measures temperature.

HI 9812 is supplied complete with pH/EC/TDS probe, HI 1285-0 with 1 m (3.3’) cable, pH 7 calibration solution (1 x 20 mL), 1382 ppm and 1413 uS/cm calibration solutions (1 each), cleaning solution (2 pcs), blue protective case, battery and instructions. HI 9812-5 is supplied complete with pH/EC/TDS/T HI 1285-5 with 1 m cable, pH 7 calibration solution, 1382 ppm and 1413 ?S/cm calibration solution (1 each), cleaning solution (2 pcs), blue protective case, battery and instructions.

HI 9813-0 • HI 9813-5 - Rugged pH/EC/TDS Meters for Growers

HI 9813-0 allows you to measure pH, EC (conductivity) and TDS with just one instrument! The meter has a pH measurement range that covers the full spectrum. The EC range goes to 4.00 mS/cm. In the TDS range, both instruments use a conversion factor from 0.56 to 0.72 for fertilizer readings, to ensure your measurements fully conform to industry standards. HI 9813-0 and HI 9813-5 measure TDS in the 0 to 1999 ppm range. The specially engineered HI 1285-0 probe is interchangeable and the pH electrode utilizes a fiber junction and gel electrolyte which are particularly suitable when used in fertilizer solutions. HI 9813-5 also performs temperature measurements, with the special probe HI 1285-5.

HI 9813-0 is supplied complete with pH/EC/TDS probe HI 1285-0, 1 m cable, pH 7 calibration solution (1 x 20 mL), 1.41 mS/cm and 1500 ppm (1 each) calibration solution, cleaning solution (2 pcs.), blue protective case, battery and instructions. HI 9813-5 is supplied complete with pH/EC/TDS/T HI 1285-5 1 m cable, pH 7 calibration solution (1 x 20 mL), 1.41 mS/cm and 1500 ppm (1 each) calibration solution, cleaning solution (2 pcs.), blue protective case, battery and instructions.

HI 9813-6 - F.S.T. - Fail Safe Technology Water-Resistant pH/EC/TDS/T Combined Meter

A common pH electrode provides an output signal equal to 0 mV if immersed in a solution at pH 7. This output value can also be obtained in case of anomalies such as:
• A broken bulb in the pH electrode
• A short circuit in the cable or connector
• Magnetic force leakage in the cable or connector (for example, in case of excessive humidity)

In these conditions, an instrument will show a false reading of pH 7 on the display, so the user isn’t able to identify that corrective measures are necessary. To avoid this problem, HANNA instruments ® developed new F.S.T. technology for the new HI 9813-6. With this special security system, if the meter encounters incorrect readings, the instrument doesn't’t display values close to pH 7, but close to pH 4, making the problem clear to the user. To allow maximum confidence in your measurements, the meter is equipped with two LEDs and a “Check” button. When pressing this button, after immersing the electrode in the proper solution, HI 50021P (Cal-Check solution), one of the LED’s will light up to indicate the status of the meter. The green LED (“OK”) indicates the probe is working correctly, while the red LED (“C&C” Clean & Cal) indicates the electrode needs attention.

HI 9813-6 is supplied complete with pH/EC/TDS/T HI 1285-6 probe with 1 m (3.3’) cable, pH 7, 1.41 mS/cm and 1500 ppm calibration solution (20 mL each), cleaning solution (2 pcs), HI 50021 test solution (2 pcs), blue protective case, battery and instructions.

HI 991300 • HI 991301 - Waterproof pH/EC/TDS/Temperature Meter with Advanced Features

HANNA instruments offers you a choice of 2 meters to meet your exacting requirements. HI 991300 and HI 991301 offer you the combination of pH, electro-conductivity, total dissolved solids and temperature measurements. To increase precision, you can select the meter which will work best with your range of conductivity, from purified to brackish waters. There are only 2 buttons, yet you can select from a range of calibration buffers and even the temperature scale (°C or °F) most familiar to you. The housing is waterproof and rated for IP 67 conditions. The multi-parameter probe, HI 1288, includes pH, EC/TDS and temperature in one convenient, rugged handle. Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients (?) from 0.0 to 2.4% for greater consistency and reproducibility. Also selectable are standardized buffer recognition values. To ensure against interference from transient electrical noise, a solid-state amplifier is integrated into the probe.

HI 991300 is supplied complete with pH/EC/TDS/T HI 1288 probe, with 1 m (3.3’) cable, batteries, rugged carrying case and instructions. HI 991301 is supplied complete with pH/EC/TDS/T HI 1288 probe, with 1 m (3.3’) cable, batteries, rugged carrying case and instructions.

HI 255 - Combined pH/ORP and EC/TDS/NaCl Meter for Laboratories

The new HI 255 is the product of 26 years of instrument testing and design experience. It is the first laboratory bench meter to simultaneously perform precise, repeatable pH and conductivity measurements. This meter was designed to satisfy the requests of many production and quality control laboratories that need quick multiple parameter measurement results with a single precision instrument.The pH and conductivity circuits have been electrically separated, so that it is not necessary for the two probes to be simultaneously immersed in the same solution. The conductivity probe will not interfere with your pH measurements and the response of the pH electrode is immediately stable.

HI 255 is a high performance instrument that measures within a wide range of multiple parameters. With this single laboratory bench meter you can perform pH, ORP, conductivity, TDS, NaCl percentage and temperature measurements. pH measurements are automatically compensated for temperature, thanks to the external probe included with the instrument. pH calibration is possible in 1, 2, or 3 points between the 5 available memorized buffers, to ensure a higher level of precision. EC measurements can be compensated according to a reference temperature of 20 or 25°C. The most suitable range of EC and TDS is automatically selected, and EC calibration can be performed at 1 point. EC calibration can be chosen between 6 memorized buffers. Thanks to the logging function, measurements are stored in non volatile memory, and can be downloaded to a PC through the RS232 serial port. In addition to these features, HI 255 is rounded out with GLP features that store the calibration data of any measurement to be displayed upon request.

HI 255 is supplied complete with HI 1131B pH electrode, HI 76310 conductivity probe, HI 7662 temperature probe, HI 76404 electrode holder, pH 4 and pH 7 buffer solutions, HI 7071S electrolyte solution, 12 Vdc power adapter and instructions.
