It is often necessary to take temperature measurements with different types of thermocouples.
To make this possible in a single meter, Hanna developed HI 93542 and HI 93552 dual-channel, waterproof K, J and T-thermocouple thermometers. These professional grade instruments will switch between thermocouple types and linearise the readings taken with each. HI 93542 and HI 93552 offer a resolution of 0.1 from -149.9 to 999.9°C and -24.9 to 999.9°F with a HOLD button to freeze the display for easy recording. At any time, you can switch views to see all continuously updating information on either channel. Current temperature can be shown along with the high, low or average values. The current or average difference between channels is displayed with the temperature at both probes or the high/low of the difference. Finally, you can set a relative temperature at each channel and then see the variance from that reference point. HI 93542 and HI 93552 both read in °C and °F. The HI 93552 allows auto-calibration at 0°C in a simple ice bath. HI 93552 can also store a reading, has selectable auto off and a backlight for low light conditions. All features are easily performed with single handed operation.
HI 93542 is supplied complete with batteries, protective case and instructions.
