Digital Thermometer TL1-R ThermoProbe |
|
Product Description |
|
The TL1-R is an intrinsically safe precision thermometer designed for use in hazardous locations. The TL1-R is a compact reference with accuracy comparable to instruments costing twice as much. The TL1-R is well suited for establishing temperature traceability in equipment that requires high accuracy. The TL1-R is also perfect for metrology applications and as a calibration reference thermometer. It is an extremely accurate portable hand held instrument that is ideally suited for field applications and indoor laboratory uses. There is no other digital thermometer with this accuracy in such a small package. |
|
The versatile software functions allow easy selection of Celsius or Fahrenheit units and display resolution. Encoded calibration is unaffected by temperature, vibration, or battery removal. Low battery display, and failure mode indications protect the user from false data. The intuitive display indicators allow the user to establish accurate temperature readings. Minimum, maximum and average temperatures are automatically stored to memory for later reference |
|
The TL1-R is constructed with a robust aluminum case and stainless steel temperature probe. Different from most electronic thermometers, the “Cordless” TL1-R has no wires to get in the way or break. The sealed overlay switch interface makes for intuitive operation. Standard probe lengths are 8 and 12 inches with additional lengths available upon request. The TL1-R comes equipped with easily replaceable AAA batteries, providing up to 200 hours of operation |
