Sauter JIT 100 infrared thermometer -32 to 420 °C, 12:1, locked measurement

The Sauter JIT models are infrared thermometers designed for non-contact measurement of surface temperature. The JIT 100 covers a range from -32 °C to 420 °C with a distance-to-spot ratio of 12:1, whilst the JIT 200 covers a range from -32 °C to 1,100 °C with a ratio of 20:1. Both feature an EBTN colour display, a laser for marking the measurement point and a limit value alarm function. The JIT 200 also has a data memory with date and time and a dual laser.

Distance-to-spot ratio and measurement spot

The distance-to-spot ratio (D:S) indicates the size of the measurement spot at a given distance. At a ratio of 12:1, the JIT 100 detects a 1 cm spot from a distance of 12 cm; at a ratio of 20:1, the JIT 200 detects a 1 cm spot from a distance of 20 cm. The higher the ratio, the further away from a small object you can take a measurement. The response time is 250 ms; the data sheet specifies a range of 0.1 to 1.0 for the emissivity.

JIT 100: up to 420 °C, with locked measurement

The JIT 100 measures from -32 °C to 420 °C. According to Kern, the tolerance range is ± 1.5 °C or ± 1.5 %. A Class 2 laser (less than 1 mW) marks the measurement point. The locked measurement protects processes that require temperature monitoring: the measured values are locked and protected against external influences. The device has a mounting hole for a tripod.

JIT 200: up to 1,100 °C, with memory and hold function

The JIT 200 measures from -32 °C to 1,100 °C and is suitable for high temperatures on furnaces, melts and heat treatment plants. The dual laser makes positioning easier. Timed measurements are possible, and the memory stores up to 99 measurement data points with date and time. It also features hold, peak hold and statistics functions, and the unit can be switched between °C and °F. A mounting thread accommodates a tripod.

Common functions

Both devices store MAX, MIN, AVG and DIF, that is, the highest, lowest and average values over a period of time, as well as the difference between the highest and lowest values. The limit value alarm function signals with an audible signal and a three-colour LED when the measured temperature falls below or exceeds the set limit value. Five presets are available for the alarm limit value and the emissivity. The device runs on a 9 V block battery for up to 9 h and switches off after 15 s of inactivity.

Typical applications

• Metalworking and mechanical engineering: surface temperature on machines, bearings and workpieces
• Environmental technology: temperature checking of systems and pipework
• Agriculture: temperature measurements on storage facilities, equipment and livestock housing
• Laboratories and quality control: non-contact temperature measurement on samples and components
• Maintenance and service: inspection of electrical and mechanical systems, including wind turbines

The JIT 100 is suitable for most maintenance tasks up to 420 °C. Those who measure above 420 °C or want to store time-stamped measured values need the JIT 200.
