Product information "Sauter JFT 100 food thermometer infrared and probe, -40 to 300 °C, IP65"
The Sauter JFT 100 combines two thermometers in a single device: an infrared sensor for surface temperatures ranging from -40 °C to 300 °C and a fold-out probe for measuring the core temperature of foodstuffs from -50 °C to 300 °C. At goods receipt, you first check the packaging without contact and then the internal temperature of the goods. The device is protected against dust and splashing water to IP65, and the display can be rotated by 180°. A single laser marks the measurement spot in infrared mode.
Infrared and probe
In infrared mode, the JFT 100 measures with a distance-to-spot ratio of 8:1 and a tolerance of ± 1.5 °C. At a ratio of 8:1, the device measures a spot of 1 cm from a distance of 8 cm. The infrared mode is suitable for surfaces such as packaging, shelves and cold store walls, whilst the probe is designed to measure the temperature inside food and goods. According to Kern, the tolerance for the probe (K-sensor) is ± 1.0 °C, the readability is 0.1 °C and the repeatability is 1.0 °C. The probe requires a minimum immersion depth of 12.5 mm. The T1-T2 function shows the difference between two measuring points, for example between surface and core or between flow and return.
HACCP, hold and display
A temperature range display supports checking according to HACCP guidelines, as Kern states. Hold, peak hold and averaging functions, as well as a limit value function, are available. The unit can be switched between °C and °F. According to Kern, two AAA batteries last up to 40 h; the auto-off function switches the unit off after 1 min or 10 min.
Material and robustness
The housing is made of stainless steel and plastic and measures 55 x 28 x 178 mm. Kern specifies FDA-compliant materials and describes the device as drop-proof up to 1 m. It weighs approx. 0.20 kg.
Typical applications
- Food inspection: goods receipt and in-house checks, surface and core temperatures
- Storage and transport: checking chilled and frozen goods
- Catering: temperature checking of food, refrigeration areas and kitchen surfaces
- Retail: testing refrigerated display counters and fresh produce
The JFT 100 is designed for use with foodstuffs. For industrial surfaces up to 420 °C or 1,100 °C there are the JIT series infrared thermometers, for continuous monitoring the JTL 100 data logger, both also available.
