HI 993301 • HI 993302 - EC / TDS / Temperature Monitors with Back-lit Display for Agriculture

These indicators from Hanna have a large, dual-level, back-lit LCD to give instantaneous readings of both EC/TDS and temperature even from a distance. The waterproof EC/TDS indicators HI 993301 and HI 993302 have been designed to meet the Grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. At startup, HI 993301 and HI 993302 perform a self-check to assure proper working condition. These powerful instruments also feature a stability indicator and hold feature to prompt the user when to take the reading and freeze the display for easy and accurate recording. Calibration and temperature compensation is automatic, while the EC/TDS conversion factor and temperature coefficient factor (?) are user adjustable for application specific measurements. Choose your EC/TDS indicator according to the proper EC/TDS ranges for your application:

· HI 993301: EC - 0 to 3999 ?S/cm; TDS - 0 to 2000 ppm
· HI 993302: EC - 0.00 to 20.00 mS/cm; TDS - 0.00 to 10.00 ppt

HI 993301 is supplied complete with HI 7630 EC probe, 1413 ?S/cm calibration solution (20 mL), 12 Vdc adapter and instructions.

HI 993302 is supplied complete with HI 7630 EC probe, 12.88 mS/cm calibration solution (20 mL), 12 Vdc adapter and instructions.

HI 983303 • HI 983306 • HI 983307 • HI 983308 - Water-Resistant EC/TDS Meters with Visual Alarm

Water-resistant conductivity/TDS meters are Hanna’s reply to requests of accurate process monitoring at highly affordable costs with low maintenance. Four different models are available to cover all applications. Each meter is supplied with a direct 2-pin probe and 2 meter (6.6') cable with a 1⁄2" thread for flow-thru mounting. The probe has a temperature sensor to automatically compensate against temperature changes from 5 to 50°C (41 to 122°F) with a ? of 2% per degree. In the measurement mode, a red LED will warn the user in the event the reading is outside of the alarm interval. A front trimmer allows manual calibration at 1 point. The electrical circuitry is tightly sealed inside the water-resistant enclosure. EC and TDS can be installed
anywhere quickly and easily with the casings molded hook. The specially designed casing is stable and will not roll off a table. The 12 VDC power supply allows continuous monitoring over extended periods of time.
