In an era where environmental monitoring is critical, a portable temperature and humidity meter that combines accuracy, portability, and smart design is indispensable for homes, laboratories, and industrial applications.
Core Features & Technical Specifications of Temperature and Humidity Gauge
1. Dual High-Precision Sensors
- Temperature Range: -40°C to 80°C, ideal for extreme environments like freezers, workshops, and outdoor settings.
- Humidity Range: 0%RH to 100%RH, enabling full-scale moisture detection in dry or humid conditions.
- Measurement Accuracy:
- Temperature: ±0.5°C (under standard conditions).
- Humidity: ±2%RH (within 20%~80%RH range), meeting professional-grade requirements.
2. LCD Backlight Display & User-Centric Design
- High-Contrast LCD Backlight: Ensures readability in low-light or bright environments, with one-touch backlight on/off for energy efficiency.
- Dual-Parameter Display: Shows real-time temperature (°C/°F switchable) and humidity simultaneously, eliminating interface switching.
- Compact & Portable: Pocket-sized design with lightweight construction for wall-mounting or on-the-go use.
3. Long Battery Life & Durability
- Power Source: 2 AAA batteries with 200+ hours of continuous operation (backlight off).
- Auto Shutdown: Activates after 10 minutes of inactivity to conserve power.
- Protection Rating: IP68 dust resistance, suitable for daily use.
4. Advanced Functions & Modes
- Data Hold: Freezes current readings for easy recording.
- Min/Max Memory: Tracks peak temperature and humidity fluctuations over time.
- User Calibration: Manual calibration ensures long-term accuracy.
What is The Key Applications & Solutions of Temperature Humidity Gauge
