Humidity/Temperature Datalogger, Counting Scale
Extech Instruments has two new instrumentation products: a humidity/ temperature datalogger and a battery-operated counting scale.
Humidity/temperature datalogger, Model 446580, measures from 10 to 95% relative humidity with 3% accuracy and temperature from -4 to 140 F. Humidity is measured via capacitance sensor and temperature via a semiconductor sensor. Both measurements are displayed at the same time; a 'data hold' function freezes the readings.
Built-in memory stores up to 7000 measurements at sample rates of 1 to 65 sec. Data with date and time can be transferred to a PC via RS-232. Unit comes with Windows 95/98-compatible software and cable, carrying case and 9 v battery. Price is $299.
Battery-operated counting scale, Model 160273, weighs and countssmall parts with an accuracy ratedat 0.02%. The LCD indicates weight, piece weight and quantity. Weightcapacity is 26 lb and is displayed with 0.005 lb resolution.
Features include Tare and AutoZero tracking, a memory function that stores count and weight values and a large stainless steel platform. Priceis $599.
