The DT4253, which is part of Hiokis DT4250 series of standard digital multimeters, is ideal for measuring instrumentation, air conditioning equipment, and gas-burning devices.
- 600.00 uA range for measuring very low currents used by gas-burning devices
- The instrument can convert and display instrumentation signals of 4 to 20 mA or 0 to 20 mA representing properties such as temperature, pressure, and flow rate from a transducer or other device that converts sensor data into an electrical signal.
- Mistakenly measuring voltage using the current range may lead to a short-circuit. The DT4253 eliminates the root cause of such accidents by providing clamp-on sensor based current measurement functionality instead of using conventional probes.
- Measure output voltage on the secondary sides of inverters by eliminating harmonic components
- To ensure operators ability to use measuring instruments safely, IEC 61010 classifies the locations in which instruments are used into a series of safety-based measurement categories (ranging from CAT II to CAT IV). Using an instrument that does not satisfy the required safety level can lead to an electrical accident.
