Hanna Instruments introduced the first Checktemp® thermometers that incorporated a unique calibration check feature used to determine any drift of the internal electronics. A switch was used to place the thermometer in CAL Check mode. If the reading is inside +/- 0.3 °C from the 0.0 °C reference point then the internal electronics are working correctly. Today’s meters do the check at start up to know if the meter is working properly.
The range of testers available include stick style, folding probes, and weighted probes. We offer both thermistor and K-Type thermocouple technology based on the measurement range needed. Many meters have CAL Check, a certificate stating the accuracy that is traceable to a NIST standard, automatic shut off, and wake on motion. We also offer versions that are EN 13485 certified.
The HI151 Checktemp® 4 is a folding thermistor thermometer that can measure temperature up to 300 °C (572 °F). These thermometers offer many advanced features including CAL-Check for an internal verification of the electronics and a motion sensor which eliminates the need of closing and reopening the probe when the meter enters a power saving mode. The Checktemp 4 is available in six different colors which can be assigned to different products to avoid cross contamination in the restaurant, kitchen or production facility.
Checktemp® 4 has an ergonomic design that fits comfortably in the hand. The meter uses vulcanized rubber that is available in 6 different colors for a non-slip grip.
The Checktemp thermometer is completely waterproof to IP67 standards. The IP67 standard is for continuous immersion in water up to 1 meter (3′) in depth. The meters will actually float if accidentally dropped into a pot, vat or any other container.
The sharp, AISI 316 stainless steel probe is ideal for testing fresh, cooked and semi frozen food. The NTC thermistor is located in the sensing tip and allows for the measurement of food that is 2 cm (0.79″) thick.
HI151 is calibrated to five points (-20.0, 0.0, 25.0, 60.0 and 120.0 oC) and tested at three points using reference meters, the accuracy of which is traceable to NIST in the USA or an internationally acceptable national physical standards. Each meter is serialized and supplied with an instrument quality certificate
With all thermometers there is drift in the electronics over time. Every time the thermometer is switched ON the LCD will display “CAL” then “-0-”, indicating that the factory calibration has been verified and the thermometer is ready for use.
The meter has an adjustable power save mode that can be disabled. The power save mode can be programmed to turn the display off and conserve power after 1, 2, 8, or 60 minutes. The built-in motion sensor detects when the meter is picked up and automatically turns the display back on.
