About Wahl

Palmer Wahl Instruments Inc. is an ISO 9001: 2015 certified manufacturer of precision temperature and pressure instruments. The company's catalogue includes thermal imagers, thermometers, pyrometers, temperature-sensitive labels, thermowells, calibrators, probes, pressure gauges, test gauges and soldering iron testers. The brand's digital thermometers can measure temperatures between -328 and 1472 degrees F. These battery-operated thermometers feature an RTD sensor, a large LCD screen and a NEMA-4X stainless steel housing and use continuous self-checking technology to provide accurate readings. They feature a stepped-shank design with a reduced diameter at the tip compared to the base of the shank. This unique construction enhances the thermowell response time, making it particularly suitable for applications where a fast and accurate temperature response is crucial. Wahl Thermowells come with a tapered shank, providing optimal compatibility with temperature instruments. The taper ensures a secure and effective fit for stem assemblies. These thermowells feature stainless steel construction for durability and resistance to corrosion. They are equipped with a 3/4 inch MNPT (Male National Pipe Thread) for ease of installation. These thermowells further feature an insertion length of 2-1/2 inches combined with a 1-1/4 inch NEF (National Extra Fine) thermometer thread connection for precise and reliable temperature monitoring.
