ngineered to continuously monitor pH (0.0 to 14.0 pH), TDS (0.00 to 10.00 g/L) or EC (0.00 to 20.00 mS/cm) and temperature. This microprocessor based meter feature a large, dual level, backlit LCD to give instantaneous readings of pH, EC or TDS and temperature. Optimized for hydroponic and greenhouse applications, the meter housing and cable connections have been sealed against vapor and humidity.
-Waterproof
-Automatic Temperature Compensation (ATC)
-Large, backlit LCD screen for easy reading
The HI991405 is a simple way to measure pH, TDS (0.00 to 10.00 g/L) or EC (0.00 to 20.00 mS/cm) and temperature. Installation is easy; simply hang the meter right above the sample to be tested for continuous measurement, plug the instrument to the mains, immerse the probes and the unit will run without interruption on 12v DC power supply. The large dual-display LCD screen shows pH, TDS or EC and temperature readings simultaneously. Designed for use in greenhouses and horticultural applications, this meter is waterproof and protected against the ingress of dust and particles.
The meter is supplied with a HI1293D pre-amplified pH electrode with a PEI body and a DIN connector. The amplifier for the pH electrode prevents interference from humidity and sources of electrical noise including circulating pumps, motors and ballasts for grow lights. The polyethylenimine (PEI) protective body protects against most aggressive chemicals as seen in fertilizer solutions with high concentrations of phosphate and nitrate.
The fixed conductivity probe, HI7630 2-pin amperometric features a built-in temperature sensor, 2m (6.6') cable and protective sleeve to resist most aggressive chemicals. Calibration and temperature compensation are automatic, while the EC/TDS conversion factor and temperature coefficient are user adjustable for application specific measurements. Additionally both the HI1293D pH electrode and HI7630 conductivity probe have been molded with pipe thread (1/2" NPT) which allows the user to attach them to an in-line system.
