E Instruments has just released its TH300 humidity and temperature sensor, which is ideal for applications that require a single, high-accuracy instrument. The sensor measures relative and absolute humidity, dew point, wet and dry temperatures, and enthalpy. The range of measurement is from 0% to 100% relative humidity and – 40F to 356F. Accuracy is ±1.5% RH and ±0.45F. The sensor can display up to four simultaneous parameters and includes all the standard transmitter output options. (www.e-inst.com)
