Martindale DTL84 Multi-Input Data Logging Thermometer

The Martindale DTL84 Multi-Input Data Logging Thermometer has four channels compatible with a variety of thermocouples (type K, J, E, T, N, R, S). It can measure temperature from -200˚C to 1700˚C depending on the probe and accuracy can be as good as ±(0.1% + 0.7˚C) with a type J, K, E, T or N probe. Readings have a maximum resolution of 0.1˚C.

Four temperature readings can be shown simultaneously on the Martindale DTL84’s large digital screen in either Fahrenheit or Celsius and there is a data hold function that freezes a reading on screen. Additionally, a min/max/avg recording function allows the user to view extreme and average values as necessary, including when measuring over a longer period.

As a data logging instrument, the Martindale DTL84 is capable of storing results in its onboard memory as a spot reading or as part of longer-term monitoring. Data transfers can be performed via the USB port to a PC or by using the supplied Bluetooth adaptor to form a wireless connection with an iOS or Android smart device (app required). A data transfer software package is provided to facilitate manual downloads.

As standard, the Martindale DTL84 comes supplied with two type K thermocouples that have a temperature range of -50˚C to 200˚C and a probe accuracy of ±2.2˚C. Further accessories include the Bluetooth adaptor, a micro USB cable, 4 x 1.5V AA batteries, a software CD, a storage case and an instruction manual.
