SIR2, SPK1 Pocket IR and Pocket-knife Style Thermometers Feature Faster and More Convenient Readings

BREA, Calif., February 7, 2005 -- Fieldpiece Instruments, supplier of modular, professional-grade instruments for field service, announces the immediate availability of two new pocket thermometers, the SIR2 Pocket Infrared (IR) Thermometer with laser, and the SPK1 Pocket-knife Style Thermometer. The two new products are designed for quick temperature readings of registers and ambient temperatures, both indoor and outside.

The SIR2 Pocket Infrared (IR) Thermometer utilizes a laser to identify the target. With the SIR2, the technician can take ambient air temperatures by “shooting” any representative surface immediately after pulling it from his pocket. There’s no need to wait for stabilization. The viewing ratio is 3:1, which means that you can “shoot” a 6” register from a foot and a half away. You can also measure the temperature of a 4-foot section of wall from 12 feet away.

The SPK1 thermometer is like the common rod-type thermistor thermometer except that it folds in half. The probe folds into the body for storage and protection, making it much easier to carry than a non-folding thermometer. Detents allow the technician to open the probe part way so he can hang it from a vent or thermostat for safer hands-free measurement. The detents hold the rod at any angle. Because the rod folds away like a pocket-knife, there is no cover or sleeve to lose.

“These two pocket thermometers, even though they use different technologies, can make the technician’s job a little easier and faster,” said Rey Harju of Fieldpiece Instruments. Both thermometers fit nicely in a pocket, display temperature at 0.1°F resolution, both have easy to read displays, both have a MIN/MAX and HOLD mode, have a Hold button to freeze the display, both have auto off, both can display °F or °C. The temperature ranges are -27°F to 482°F (SIR2) and -58°F to 392°F (SPK1). Accuracies from 0°F to180°F are +/- 3.6 °F (SIR2) and +/-1.8°F (SPK1).
