Thomas ABS Plastic Traceable Digital Humidity and Temperature Meter with 3/4" High LCD Display, 3-7/8" Length x 2-5/8" Width x 5/8" Thick
Routine measurements, monitoring round-the-clock, quality-control needs, and critical experimental requirements are features of this humidity/temperature meter. Unique instrument shows the exact air conditions in labs, hoods, clean rooms, coolers, stockrooms, incubators, environmental chambers, and chemical storage areas. Continuously and simultaneously displays relative humidity and temperature in degree F/ degree C with dual-recall memories. Minimum and maximum memories may be displayed or cleared at any time with the touch of a button. Monitors conditions overnight, on weekends, or for any time period. Temperature range is 32 to 122 degree F and 0 to 50 degree C with a resolution of 1 degree and accuracy of +/-1 degree C. Humidity range is 25 to 95 percent, resolution is 1 percent RH, and accuracy is +/-2 percent RH mid-range to +/-4 percent RH elsewhere. Fast-response solid-state sensors show changes in less than 30 seconds. Display is updated once per second. To assure accuracy an individually serial-numbered Traceable Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Extra-large, easy-to-view 5/8-inch-high digits can be read at a glance from as far away as 20 feet. Meets federal requirements for CLIA specification 493.1252 for monitoring temperature and humidity. Self-contained, stable, accurate unit requires no adjustment or maintenance. Case is chemical-and shock-resistant ABS plastic. Supplied with Traceable Certificate, wall mount, bench stand, switch to read degree F/ degree C, fast-response solid-state sensors, and two AAA batteries. Measures 3-7/8" length by 2-5/8" width by 5/8" thick. Weight is 2-1/2 ounces.
