A triple display constantly shows high, low, and current temperatures. Instantly view if freezer, water bath, or incubator is within temperature spec. Monitor temperature of any experiment when you’re not there- overnight, weekends, even during lunch. Range is -58 to 158°F or -50 to 70°C. Resolution is 1° and accuracy is ±1°C. Sensor and 10-foot cable may be placed under water, in refrigerator, or freezer. Small cable diameter (1/16 inch) allows refrigerator doors to close on it with no effect. Unplugging the cable activates a sensor inside the unit for monitoring ambient room temperature. Simple one-button operation resets the high/low memories. Probe’s wire-mounting bracket permits easy sensor placement. Low battery is signaled on the display. Unit’s high-impact ABS plastic case has a flip-open stand, wall hanging hook, magnet, and VELCRO mounting tape. Size is 2-5/8 x 2-1/2 x 3/4 inches. Unit runs continuously for 1 year on the supplied battery.
