Measuring Instruments

Category Overview

The Measuring Instruments category covers the equipment needed to accurately determine critical values such as temperature, heat distribution and thermostatic control in combi boilers, central heating, plumbing and general heating and cooling systems. Addressing a wide audience, from service technicians to plumbing and heating installers and from industrial maintenance staff to hobby users, these instruments form the basis of fault diagnosis and correct adjustment. Using professional equipment to measure the flow-return water difference of a combi boiler, the surface temperature of a radiator or the ambient temperature of a control panel both saves time and prevents parts being replaced because of a wrong diagnosis.

Products You Can Find in This Category

The Yedepa.com Measuring Instruments section contains calibratable, field-tested products suited to different usage scenarios. Solutions are offered across a wide range, from liquid, surface and air temperature measurements to temperature-based relay control. The featured product types are:

• Digital Probe Thermometer TPM10: Ideal for liquid and closed-line temperature measurements; thanks to its probe length it can easily be used inside a boiler or hot water cylinder.
• WT-1 Digital Pen Thermometer (-50°C / +300°C): With its wide measuring range it can be used in every field, from food to industrial applications.
• XH-W3001 Digital Thermostat 220V 1500W: An economical control module that triggers a device according to a temperature threshold, preferred in DIY and professional projects such as incubators, aquariums and refrigeration systems.
• WH380 Laser Infrared Thermometer (-50°C ~ 380°C): Provides quick diagnosis at points such as motors, boilers, flues and air conditioner evaporators by taking non-contact measurements.
• WTY-100B Analogue Mechanical Thermometer: A durable classic solution that needs no electricity and works panel-mounted.

Selection Criteria and Tips

Choosing the right measuring instrument depends on the environment you will measure and your accuracy requirement. While probe thermometers are preferred for moving fluids and closed systems, non-contact laser infrared thermometers provide both safety and speed on rotating or live electrical surfaces. If you are setting up automation, relay-type digital thermostats such as the XH-W3001 can trigger an actuator. When choosing an instrument, pay attention to the measuring range (e.g. -50°C / +380°C), the accuracy value (±0.5°C / ±1°C), the probe material (stainless steel is preferred) and the supply type (battery, 220V AC or 12V DC). If several points are being measured in the field, the laser + probe combination is the most practical solution.
