Precise Environmental Monitoring with the Humidity/Temp. Meter HTD181

Maintain optimal environmental conditions in laboratories, cleanrooms, storage facilities, and HVAC systems with the Humidity/Temp. Meter HTD181—a compact, high-accuracy instrument that simultaneously measures relative humidity (RH) and air temperature with professional-grade reliability. Designed for quality control, compliance, and preventive monitoring, the HTD181 delivers fast, stable readings to help you protect sensitive samples, equipment, and processes.

Professional-Grade Accuracy in a Portable Design

The HTD181 Humidity/Temp. Meter uses a high-stability capacitive humidity sensor and precision NTC temperature sensor to provide reliable measurements across a wide range: 0–100% RH and -10°C to +60°C (14°F to 140°F), with ±2% RH and ±0.5°C accuracy. Its large, backlit LCD displays both parameters simultaneously, along with dew point and wet-bulb temperature—critical metrics for environmental assessment.

Dual-Parameter Display – Shows real-time humidity, temperature, dew point, and wet-bulb values on one screen.
High Accuracy & Stability – ±2% RH and ±0.5°C ensures trustworthy data for GMP, ISO, and HACCP compliance.
Data Hold & Min/Max Recording – Capture peak and trough values over time for trend analysis and reporting.
Compact & Portable – Pocket-sized with a protective holster; ideal for spot checks or routine audits.
Auto Power-Off & Low Battery Indicator – Extends battery life (typically >200 hours) and prevents unexpected shutdowns.
Calibration Certificate Available – Optional NIST-traceable documentation for regulated environments.

Trusted Across Critical Applications

From monitoring vaccine cold chains and pharmaceutical stability chambers to validating cleanroom conditions or assessing mold risk in buildings, the HTD181 provides the environmental insight you need to act proactively. Its fast response time (<10 seconds) and rugged design make it equally suited for field technicians, lab managers, and facility engineers.

Whether you’re ensuring product integrity or occupant comfort, the Humidity/Temp. Meter HTD181 delivers professional performance—simply, reliably, and affordably.

Control your climate. Protect your processes.
