Description
The WIKA CTH7000 is a two-channel hand-held precision thermometer for Pt100/Pt25 resistance thermometers and NTC thermistors, measuring from −200 to +962 °C (depending on probe) with 0.015 K accuracy, 0.001 °C resolution and drift below 0.005 °C per year. It can show both channels or the difference between them.
SMART probe connectors keep each probe's calibration coefficients in the plug, so probes can be swapped between instruments without re-entering data. It logs about 8,000 readings, calculates statistics, connects to a PC over USB and runs about 20 hours on its rechargeable battery.
Argonmark Ltd supplies WIKA instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
