Green Mark Sensor Provider

We are proud to support Singapore’s BCA Green Mark initiative through our locally manufactured Green Mark Sensors, designed for accurate monitoring in energy-efficient building systems.
Each sensor is calibrated under our in-house SAC-SINGLAS ISO 17025 accredited laboratory, ensuring precision, compliance, and reliability in achieving Green Mark standards for sustainable performance.

Sustainable Temperature Solutions

We manufacture precision temperature sensors fully compliant with SS 591, delivering the ±0.05 °C accuracy required for Green Mark chilled water systems.

  • Designed and manufactured in full accordance with SS 591
  • High-accuracy thermistors (±0.05 °C) for chilled water inlet/outlet measurements
  • Built-in test ports / thermowells for fast validation and commissioning
  • Robust, weather-resistant housing suitable for harsh plantroom conditions
  • Compatible with all major BMS and data acquisition systems
  • Supported by ISO 17025–accredited calibration, ensuring traceability and confidence.

Our ISO 17025 accredited laboratory is among the very few in Singapore capable of performing precision calibration for RTD (PT100 / PT1000) and even thermistors—delivering ultra-low measurement uncertainty below 0.01 °C (10 mK) for full Green Mark compliance.

GreenMark Sensor

BCA Green Mark Sensor Provider in Singapore

Achieving a high-tier BCA Green Mark rating for your building isn’t just about general efficiency—it is about the precision of your data. To optimize a Chiller Plant’s efficiency, the measurement of chilled water temperatures must be flawless. Even a slight error in sensor readings can lead to significant energy waste and a failure to meet strict regulatory benchmarks.

At Thermotron-CE, we specialize in manufacturing high-precision Green Mark sensors designed specifically for Singapore’s sustainable building landscape.

Precision Compliance with SS 591 Standards

General-purpose sensors often fall short of the rigorous demands required for Green Mark certification. Our locally manufactured sensors are engineered in full accordance with SS 591.

To ensure your chilled water system operates at peak performance, we utilize high-accuracy thermistors capable of delivering ±0.05 °C accuracy for both inlet and outlet measurements. This level of precision is vital for the accurate calculation of chiller efficiency (kW/RT) and for passing mandatory BCA audits.

Validated by SAC-SINGLAS Accredited Calibration

Trust is built on verification. Most suppliers outsource their testing, but we maintain complete control over quality through our in-house laboratory.

Our facility is one of the few in Singapore accredited by SAC-SINGLAS (ISO 17025) specifically for ultra-low measurement uncertainty. We can achieve uncertainty levels below 0.01 °C (10 mK), providing the documented traceability you need for seamless commissioning and fast validation. Whether you are working with RTDs (PT100/PT1000) or specialized Thermistors, our calibration ensures your data is beyond reproach.
