The HQ40d Dual-Input Digital Multi-Parameter Meter offers true Plug and Play operation with IntelliCAL™ pH, conductivity, and LDO® dissolved oxygen probes. Plug in any two IntelliCAL probes and get simultaneous measurement, simultaneous readout! "Smart" meters store probe serial numbers, calibration history, user ID, time, date and location of readings.
pH 探头显示： pH, mV, 温度
电导探头显示： selected parameter (conductivity, resistivity, TDS), temperature correction, temperature
溶氧探头显示： dissolved oxygen (mg/L, % saturation), pressure, temperature
数据储存：500 results — GLP/ISO compliant reading data stored with calibration details. Calibration details and check standard readings documented as events in log. Operates in "press to read" mode, continuous read mode, and interval measurement mode. Store data internally and/or download via USB connection to PC or flash stick.
Temperature Correction/Compensation: off/automatic/manual
显示锁定功能: Freezes results display, including time and temperature, when stability criteria are met.
自动PH缓冲液识别：Automatic pH Buffer Recognition: Choose from 3 sets: Color-coded: 4, 7, and 10 pH; IUPAC: 1.679, 4.005, 7.000, 10.012; DIN: 1.09, 4.65, 9.23
防护等*： Meter Casing: 1 meter submersion for 30 minutes (IP67)
