• Cable length of 1.2m for flexibility
• Durable ABS housing for resistance to wear

• Refrigeration systems
• Breathalyser equipment
• HVAC systems

This device uses an NTC (negative temperature coefficient) thermistor that uses changes in electrical resistance to measure changes in temperature for a high degree of accuracy.
