Test & Measurement: Digital Temperature/Humidity Logger Preaches Accuracy

The 5020A thermo-hygrometer, a digital temperature and humidity logger, accepts inputs from up to two precalibrated sensors. Each sensor has its own calibration data, and they may be mounted on the unit or remotely (up to 50 ft away). Two sensor models are available. The S model reads temperatures from 15°C to 35°C within ±0.25°C and humidity from 20% to 70% RH within ±2%. The H model reads temperature from 16°C to 24°C within ±0.125°C and humidity from 20% to 70% RH within ±1.5%. Total range for both sensors is 0°C to 50°C and 0% to 100% RH. Price ranges from $1495 to $1745. LogWare III software costs $295 for a single-PC license. Delivery is in three weeks.
