382100 Power Analyzer
The Extech 382100 is a 3-Phase Power Analyzer/Datalogger that saves data (up to 30,000 sets of measurements) on an SD card in Excel format for easy transfer to your PC. It provides a full system analysis with up to 35 parameters including: V (phase-to-phase), V (phase-to-ground), A (phase-to-ground), KW / KVA / KVAR / PF (phase), KW / KVA / KVAR / PF (system), KWH / KVAH / KVARH / PFH (system), and Phase Angle. Readings are displayed on a large, dot matrix, sun-readable, backlit LCD. It comes with three current clamps, four voltage leads with alligator clips, eight AA batteries, SD memory card, Universal AC adapter (100 to 240 V), case, and user manual.
RH600 Handheld Dewpoint Meter
The RH600 accurately measures and datalogs dew point levels in compressed air systems. This high-precision meter can help manufacturing professionals protect product quality while avoiding damaged pneumatic equipment, corrosion, and problems in cylinder and valve systems. Featuring a color graphical display, the RH600 provides clear, stable readings, allowing you to measure dew point temperature down to -50°C (-58°F) in max ambient pressure of 20 bar. Set high/low audible and visible alarms for temperature, relative humidity, and dew point thresholds. You can also easily log and transfer recorded data to a PC in CSV format to create inspection reports fast.
TM500 12 Channel Thermocouple Datalogger
The TM500 is a 12-Channel Datalogging Thermometer. This Datalogging Thermometer features 6 Thermocouple Types (J, K, E, T, R, S). Displays CH1 to CH8 or CH9 to CH12 on screen, data can be recorded from all 12 channels simultaneously onto an SD card in Excel format for further analysis. Complete with 8 AA batteries, 12 general purpose Type K bead wire temperature probes, SD card, and hard carrying case.
DO700 pH/mV/Temp/Cond/TDS/DO Meter
The 9-in-1 DO700 Kit measures DO concentration/saturation, pH, mV, Temperature, Conductivity, TDS, Salinity, and Resistivity. It features automatic salinity compensation and manual barometric pressure compensation for DO measurements. In addition, it has automatic one button calibration of 4, 7 and 10 pH with a choice of three-point calibration for better accuracy and it provides automatic temperature compensation. Complete with DO probe, pH/mV/Temp electrode, polymer Conductivity cell, pH and Conductivity calibration solutions, batteries and hard carrying case.
380260 Megohmmeter, Autoranging Digital
This autoranging megohmmeter measures insulation resistance up to 2000MΩ. Choice of 250,500 or 1000VDC test voltages. The large backlit dual display indicates test voltage output and insulation resistance. Low resistance, continuity and AC/DC voltage measurement functions. Other features include automatic discharge at the end of test, protective holster with stand, power lock on feature and data hold. Complete with test leads, carrying case and 6 AA batteries.
