| Features |
The Dickson THDX is a uniquely versatile instrument. We have combined Temperature, Humidity, and Dew Point Monitoring with an 8" circular chart and large digital display. Alarms, locking door and keypad are also standard features of the THDX. Accessories include extension cables for the instrument's probe for remote monitoring applications.
- Remote sensing capability with optional extension cords (10', 50' and 100' available)(see Accessories)
- Alarms: Audio/Visual with High/Low setting capabilities
- Microprocessor control and electronic sensing
- C/F and RH/Dew Point switchable
- Large 8" diameter circular chart
- Min/Max feature allows display of minimum and maximum readings
- User calibration
- Locking control keypad and door
- Large digital display shows two variables at once
- User selectable recording times and temperature ranges
- 1-Pt NIST Traceable Certificate of Calibration included with instrument (optional 3-Pt may be ordered)
- AC powered with battery back-up (batteries not included)
- 30 Day Money Back Guarantee

| Notes |
Using the THDx in a high humidity or dusty environment? Dickson recommends using the protective filter part # A867. The A867 fits snugly over the tip of the remote probe keeping out harmful dust and protecting the humidity sensor from possible condensation. To order, click on accessories. |
| Specifications |
Humidity Accuracy: ±2% from 0 to 60%, ±3% from 60 to 95%
Humidity Range: 0 to 95% (non-condensing)
Humidity Sensor: Monolithic IC Humidity Sensor
Temperature Accuracy: ±1.8°F (±1°C)
Temperature Ranges: User selectable; -20 to +120°F, +40 to +110°F, -20 to +50°C, +5 to +40°C
Temperature Sensor: Thermistor
Alarms: Audio/Visual with High/Low set points (warning mechanism only, no controller function) Alarm is 90 decibels
Ambient Operating Conditions: 0 to 95% RH (non-condensing), +32 to +122°F (0 to +50°C)
Calculated Dew Point Accuracy: The Dew point is calculated and because of the nonlinearity of the equation the error that would result from the possible errors of temperature and relative humidity are approximately as follows: 95% to 30% RH = ± 2°C, ±3.6°F; 30% to 10% RH = ±4°C, ±7.2°F; 10% to 5% RH = ±8°C, ±14.4°F; 5% to 0% RH = ±49°C, ±88.2°F
Calculated Dew Point Range: -22 to +122°F, -30 to +50°C
Average Response Times: 2.5 min at 63% of full scale Note: The THDx internally averages readings together. In battery mode the update rate is slowed to conserve power and since the unit takes 1 new reading per update, the response is also slowed. Battery power is recommended for back-up only.
Average Battery Life: 1 day recording mode = 2 months, 7 day = 3 months, 31 day = 4 months
Calibration: User calibration, see calibration kit below
Calibration Kit (optional): 12% (RH only-low end capsule) and 75% (high-end capsule 75% salt solution) 1 year shelf life, MSDS (material safety data sheet) available upon request
