Standard DMM that Delivers Top Safety and Reliability - Testing for Heating, Ventilation and Air Conditioning (HVAC) Applications
The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level. The DT4253 is a digital multimeter designed specifically for HVAC testing, with ±0.5% DC V accuracy, temperature and clamp sensor testing, and wide 40 Hz to 1 kHz bandwidth.
CAT IV 600 V, CAT III 1000 V

The DT4253, which is part of Hioki’s DT4250 series of standard digital multimeters, is ideal for measuring instrumentation, airconditioning equipment, and gas-burning devices.
・DC current: 60.00 μA / 600.0 μA / 6.000 mA / 60.00 mA
・Temperature: -40.0°C to 400.0°C
・Accepts an AC clamp sensor
Accurately measure the very low currents such as burner flame currents.
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.
Accurately measure the fundamental wave alone by eliminating harmonic components with the DMM’s low-pass filter function.
If you connect the DT4253 to a computer with the optional Communication Package DT4900-01, you can graph data stored in the instrument’s internal memory and display measurement results in real time on the computer. In addition, displayed measured values can be saved (in text format).
*The computer and multimeter are electrically isolated by means of optical communications so that data can be sent with peace of mind.
Digital multimeters implement two types of measurement: mean-value measurement and true RMS measurement. The two methods yield significantly different measurement results for current waveforms, which are often distorted. For accurate measurement, it is necessary to use an instrument with true RMS capability.
All development, design, and manufacturing processes for almost all Hioki digital multimeters are carried out at our Head Office in Nagano Prefecture. Some of the industry’s most advanced technological capabilities enable us to deliver products of the highest possible quality.
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.
