Measurement Channels: 2 channels (temperature and humidity integrated collection, synchronous calculation of dew point)
Temperature Range: -20℃ ~ +55℃
Accuracy: ±0.4℃ (full range interval), resolution 0.1℃
Humidity Range: 0~100 % RH (applicable only in non-condensation environment)
Accuracy: ±2 % RH (2~98% RH, 25℃ standard condition), temperature drift coefficient 0.03 % RH/K
Dew Point Calculation Range: -40℃ ~ +50℃Td, automatically stores dew point values
2. Storage and Recording Settings
Storage Capacity: 1 million sets of measurement data, large memory can continuously record for several years without exporting
Recording Interval: Customizable from 10 seconds to 24 hours, stepwise free setting
Data Security: Automatic backup of all data upon power failure / battery replacement, supports password lock to prevent tampering; abnormal values automatically mark as high contrast
Data Export Modes: Mini-USB data cable direct connection to computer / external SD card offline export dual mode Testo Instruments
3. Power Supply and Battery Life
Battery Specifications: 3 AAA alkaline batteries
Battery Life: At 25℃, with a 15-minute recording interval, the longest stable operation time is 3 years
Low Battery Alert: Screen pop-up notification of remaining battery power, early warning for battery replacement
4. Physical Structure and Protection
Size: 149 × 53 × 27 mm, weight 130g
Protection Grade: IP54, dustproof, splash-proof water, suitable for indoor warehouses and workshops
Screen: High-definition LCD large screen, real-time display of temperature, humidity, dew point, remaining battery power
Standard Accessories: Wall-mounted bracket, anti-theft lock, factory calibration certificate, 3 AAA batteries
Operating Temperature Range: -20℃ ~ +55℃; Storage Temperature Range: -20℃ ~ +55℃
5. Supporting Software System
ComSoft Basic (free standard)
Recorder parameter configuration, data curve viewing, PDF/Excel/CSV report export, meeting the needs of ordinary storage, building daily traceability
ComSoft Professional (paid advanced)
Batch management of multiple recorders, customizable temperature and humidity alarm thresholds, batch automatic generation of inspection reports
ComSoft CFR 21 Part11 (medical special)
Compliant with GMP, 21CFR Part11 regulations, supports electronic signature, audit tracking, data cannot be tampered with, dedicated for medical laboratories, pharmacies compliance evidence Deutag Instruments
III. Core Function Features
External prominent humidity probe
The probe extends independently from the body, with better air circulation, the response speed of temperature and humidity changes is much faster than the built-in sensor, and the monitoring data is more in line with the real environment.
Dew point automatic calculation and storage
In addition to temperature and humidity, it also records dew point values, suitable for controlling condensation risks (archives, precision instrument workshops, wine storage warehouses).
Anti-theft and anti-tampering design
Standard wall-mounted lock, fixed to the wall and cannot be removed randomly, preventing modification of recorded data by humans, meeting the requirements of supervision, food inspection audits.
Dual export channels USB direct connection to the computer for quick reading, SD card offline copying, suitable for multi-warehouse and multi-computer room batch inspection.
Long-term stable with low drift
The capacitive humidity sensor has strong long-term stability, with extremely small annual drift, and does not require frequent calibration, suitable for uninterrupted monitoring for several years.
Four. Main application scenarios
1. Warehouse and storage room temperature and humidity monitoring (most mainstream)
Pharmaceutical cool storage, reagent warehouse, vaccine storage room: meet GMP compliance, full traceability of temperature and humidity throughout the process
Archival warehouse, ancient book library, calligraphy and painting storage room: prevent paper from getting damp, moldy, and cracking
Wine / tea / tobacco storage: strictly control temperature and humidity to avoid product deterioration
Electronic component raw material warehouse: prevent moisture and static electricity, ensure component quality
2. Monitoring of buildings and office environments
Office buildings, computer rooms, laboratories, clean workshops, 24-hour monitoring of indoor temperature and humidity, optimize air conditioning and ventilation systems, record environmental comfort data, used for energy consumption and operation analysis.
3. Agricultural greenhouse cultivation
Long-term monitoring of flowers, seedling greenhouses, record temperature, humidity, dew point, adjust sprinkler and ventilation equipment, optimize crop growth environment.
4. Industrial production workshops
Precision processing, PCB electronic workshops, chemical raw material workshops, control temperature and humidity to avoid production defects, retain production environment records for quality inspection and traceability.
5. Museums, cultural relic exhibition halls
Environmental long-term monitoring of cultural relics and artworks, prevent temperature and humidity fluctuations from damaging collections, used for cultural tourism supervision and inspection.
