Dickson THDx - Remote Sens- Temp, Humidity & Dew Point-8" Chart THDx - Remote Sensing Temperature, Humidity & Dew Point Recorder - 8" Chart Features: The THDX is a uniquely versatile instrument. We have combined Temperature, Humidity, and Dew Point Monitoring with an 8" 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 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) Detailed 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 = u2°C u3.6°F 30% to 10% RH = u+4°C u7.2°F 10% to 5% RH = u+8°C u14.4°F 5% to 0% RH = u+49°C u88.2°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 Chart Size: 8" diameter Dimensions: 10.5" x 13.2" x 2.8" (26.7cm x 33.5cm x 7.1cm) Display Resolution: 1°F (1°C), 1% RH Display Type: LCD Mounting: Free standing or keyhole for wall mount Pen Life: 12 months depending on use Power Supply: 120V AC adapter, use 4 "D" batteries for back-up power. Power Cord Lenght: 2 meters Probe Dimensions: .91" diameter, 5.9" long (15.0 cm x 2.3 cm dia) 10" cord - RJ11 6 pin connector Recording Times: User selectable; 1, 7, and 31 day Warm Up Time: 15 minutes to stabilize Warranty: 1 year Enclosure Type & Weight:ABSWeight: 5 lbs without batteries (1.5 kg), 7 lbs with batteries (3.2 kg) Approvals: CE Includes: 1-point NIST Traceable Certificate of Calibration, two Pens, Box of 60 (-20 to +120/7 day) Charts, AC adapter, and Instructions Accessories A709 Carrying Case $70 A834 RH Calibration Kit (12% and 75%) $199 A860 10' (3.05 m) Extension Cable for Probe $39 A865 50' (15.25 m) Extension Cable for Probe $69 A866 100' (30.5m) Extension Cable for Probe $99 A867 Probe Dust Filter $15 Notes: To protect probe & increase life - please use dust filter in dusty environments or where RH exceeds 70%. Probe dust filter will slow down response time.
