Maintenance, Test & Measurement, Calibration
Three devices offered by Hanna Instruments for PH/ORP/RH/°C measurement are the HI 8614/14L, HI 8615/15L and HI 8666. Both the HI 8614/14L and the HI 8615/15L offer 4 to 20mA outputs, slope and offset calibration, and feature a high input impedance (1012 Ohm). The HI 8615/15L also offers 0 to 1000 mV output. The indicated pH range extends the full 0 to 14. These transmitters measure 165 x 110 x 90 mm.
Hanna's model HI 8666 sensor/transmitter features two separate 4 to 20 mA outputs, able to track relative humidity from 0 to 100% and temperature from -20 to +60°C. Accuracy is 2%/4% RH and 1% temperature. The device measures 79 x 49 x 140 mm.
