Differential digital thermometers allowing the user to use two type K thermocouple probes simultaneously. The display can be switched to show probe T1 or T2 temperature or the difference between probes T1 and T2 (T1-T2). This facility allows, for example, the temperature drop across radiators or the temperature rise or fall of two items to be measured.
The differential thermometer measures temperature over the range of -50 to +550°C with a 1°C resolution or -49.9 to +199.9°C with a 0.1°C resolution. Both thermometers feature a custom, LCD display with °C, T1, T2, diff, hold, open circuit and low battery indication. The thermometers incorporate an auto-power off facility that automatically turns the instrument off after approximately three minutes, maximising battery life. Now available with re-chargeable battery option!

thermocouple type K probes
Thermometers are only part of the system, of equal importance is the design of the temperature probes used to physically measure the item. ETI manufactures an extensive range of type K or J thermocouple probes to compliment the 2202 and 2203 differential thermometers.
Choose the ones that suit your needs from many options including:
• penetration probes
• fast response probes
• pipe probes
• needle probes
• heavy duty probes
• ribbon surface probes
• air/gas probes
• roller surface probes
• binder probes
• surface probes
• between pack probes
accessories
The protective PVC boot helps to protect instruments against accidental damage. The clear polycarbonate wall bracket stores the instrument safely (screws not supplied).
