The TE25 High Accuracy Temperature Sensor is a premium platinum resistance thermometer (PRT) designed for precise temperature measurement in chilled water energy metering, HVAC systems, district cooling plants, and Green Mark-certified buildings. Engineered for BTU measurement applications, the TE25 delivers exceptional long-term stability and measurement accuracy, making it ideal for Measurement & Verification (M&V) of energy-efficient cooling systems.

Manufactured with a 316L stainless steel probe for superior corrosion resistance and durability, the TE25 is available with a robust die-cast aluminium weatherproof connection head suitable for demanding industrial and outdoor environments. The sensor utilizes a Class AA platinum RTD element (Pt100/Pt1000) and is individually calibrated in an ISO/IEC 17025 accredited laboratory, ensuring traceable and reliable measurement performance.

Calibrated using the ITS-90 Water Triple Point standard, the TE25 achieves a measurement accuracy of ±0.03°C (0°C to 50°C), meeting the stringent requirements of SS591:2021 for Green Mark chilled water energy measurement systems. When paired with a certified BTU calculator and magnetic flow meter, it provides highly accurate thermal energy calculations for compliance with Singapore Green Mark and energy efficiency monitoring requirements.
