PCE Instruments PCE-313A Gray Hygrometer sku-438295411

The Gray PCE Instruments PCE-313A Humidity Monitors device (SKU sku-438295411) measures humidity, temperature, calculated dew point and wet-bulb temperature, with a Type K thermocouple connection for external temperature. Its listed size is 177 x 68 x 45 mm / 7 x 2.7 x 1.8 in.

Measurement ranges are 5 to 95% RH; 0 to 50°C / 32 to 122°F for temperature; -50 to 1300°C / -58 to 2372°F for Type K; -25.3 to 48.9°C / -13.5 to 120°F for dew point; and -21.6 to 50°C / -6.9 to 122°F for wet-bulb temperature. Resolution is 0.1% RH for humidity and 0.1°C / 0.18°F for each listed temperature measurement. Temperature accuracy is ±0.8°C / 1.4°F.

Humidity accuracy is ±3% of the measured value ±1% RH at ≥70% RH, and ±3% RH below 70% RH. Type K accuracy is ±(0.4% + 0.5°C / 32.9°F). The device has an external sensor, data hold, low-battery indication, a large LC display, a tripod connection and an adjustable sampling rate of 1 to 3600 seconds. It saves data directly to an SD card as an Excel file and can format the card in the device.

A 2 GB card is included; SD memory supports 1 to 16 GB. An optional software kit transfers data online to a PC or laptop, but software is not needed to analyze saved data. The case is described as resilient.
