Humitest System™
Product catalog summary
Overview: The Humitest System by NDT James Instruments Inc. is a specialized solution for measuring bore hole humidity in hardened concrete, ensuring structures are dry before proceeding with further construction phases.
Features and Benefits:
- Ensures dryness of structures before the next construction phase.
- Uniquely designed for concrete bore hole humidity measurements.
- Reusable probe for cost efficiency.
- Rapid response time and high accuracy with long-term stability.
- Conforms to ASTM Standard F-2170 for determining relative humidity in concrete floor slabs.
Technical Specifications:
- Probe:
- Measurement Range: 0-100% RH
- Accuracy: 0-90% +/-2% RH, 90-100% +/-3% RH
- Long Term Stability: 1% RH per year
- Response Time: 15 seconds for 90% of reading at 20°C, 30 minutes for full reading in a stabilized hole

- Sensor Diameter: 12mm
- Cable Length: 0.3m
- Probe Length: 69mm
- Housing Material: ABS Plastic
- Sensor Protection: Membrane Filter
- Bore Hole Diameter: 16mm
- Measurement Depth: Minimum 30mm
- Meter:
- Calculated Quantities: Dewpoint Temperature, Absolute Temperature, Wet Bulb Temperature
- Resolution: 0.1% RH / 0.1°C
- Power Supplies: 4 AA Batteries
- Display: 2 line LCD
- Approximate Weight: 300 g
Usage Procedure: The system involves boring a hole into the concrete, inserting a plastic tube, and allowing the humidity to stabilize. The probe is then inserted to take readings at various depths, which is crucial due to uneven moisture distribution in concrete.
Additional Features: The unit can display relative humidity and temperature in Fahrenheit or Celsius and store data for later upload.
