Ambient and probe temperatures
Unit continuously and simultaneously displays ambient relative humidity and (internal probe and external probe) temperatures in °F or °C, with dual-recall memories. External thermometer probe is supplied with a 10-foot cable. Both sensor and cable perform accurately when under water.
External probe range is –58 to 158°F and –50 to 70°C. Ambient internal probe range is 32 to 122°F and 0 to 50°C. Resolution is 1° and accuracy is ±1°C. Humidity range is 25 to 95%, resolution is 1% RH, and accuracy is ±2% RH mid-range to ±4% RH elsewhere. Fast-response, solid-state sensors show changes in less than 30 seconds. Display is updated once per second. Minimum and maximum memories may be displayed or cleared at any time with the touch of a button. They permit monitoring conditions overnight, on weekends, or for any time period. Jumbo 1-1/8-inch display may be read from as far away as 35 feet.
