physitemp BAT-12BAT-12 with carring case and stand (sold separetely)
  • Accuracy & resolution 0.1°C
  • Durable, sealed construction
  • Heavy duty carrying case for field use
  • Analog output

The BAT-12 laboratory digital thermometer is Physitemp's most popular and best selling instrument due to its versatility, quality construction and low cost.

The BAT-12 has 0.1°C resolution and super accuracy of 0.1°C ±1 digit between 0-50°C, 0.1°C ±1 digit over full range. The temperature range is -100 to +200°C. The BAT- 12 provides fast readings, usually within 2-5 seconds depending on the temperature probe in use.

The standard BAT-12 is battery operated,  providing over one hundred hours of continuous use. A rechar­geable model BAT-12R which runs on AC in the lab or on ni-cad batteries in the field is also available. All BAT- 12 thermometers are provided  with analog output for recording temperature data. The BAT- 12 Thermometer accepts all Type T thermocouple probes.

The BAT- 12 is designed with a sealed  case making it moisture, dust and fume proof so the BAT- 12 can be used not only in the lab and field but also in industrial environments as well. The BAT- 12 is supplied with a heavy duty camera style carrying case (shown above) for portable field use or can be used in the lab with the optional tabletop stand (TT S -2 shown above).
