Description
The HI-991404 combines 4 meters into one easy to use wall mounting continuous indicator.Featuring a large, dual-level, back-lit LCD display the meter can display the temperature of your solution together with the choice of either conductivity, pH or total dissolved solids (TDS).It also features a reading stability indicator and a hold feature to make it easier to write down a particular reading.Calibration and temperature compensation is automatic, while the conductivity and TDS conversion factors and temperature coefficients are user adjustable for specific application requirements.Supplied complete with a non-clog double junction pH electrode and a rugged conductivity/TDS sensor, 12volt power transformer and buffer solutions 4 and 7 together with conductivity calibration solution.For the full product specification please see the attached instruction manual.The HI-991404 is supplied complete with:HI-1293D pH eletcrodeFixed HI-7630 probepH and EC calibration solutions12VDC adapter and instructions.Product Specification SummaryRange:pH: 0.0 to 14.0 pH; EC: 0 to 3999 uS/cm; TDS: 0 to 2000 ppm (mg/L); Temperature: 0.0 to 60.0CResolution:pH: 0.1 pH; EC: 1 uS/cm; TDS: 1 ppm; Temperature: 0.1CAccuracy:pH: +/-0.1 pH; EC/TDS: +/- 2% F.S; Temperature: +/-0.5CCalibration:pH: automatic at 1 or 2 points with 2 sets of memorized buffers; EC/TDS: automatic at 1 pointPower supply:12 Vdc adapter (included)Dimensions:160 x 105 x 31 mmWeight:190gProbe:HI-7630 EC/TDS Probe (fixed)Electrode:HI-1293D pH electrode (included)
