DTLH-Mob Portable Temperature and Humidity Calibration Chamber

Overview

The DTLH-Mob Portable Temperature and Humidity Calibration Chamber is custom-designed for field testing and mobile applications. It features a 304 stainless steel inner chamber (corrosion-resistant) and an outer electrostatic spray-coated protective structure, integrated with an omnidirectional locking caster system. Its compact design significantly reduces the overall size, meeting high-frequency mobility requirements and ensuring efficient deployment for field calibration.

Product Features

• Mobile Remote Viewing & Control： Equipped with mobile APP software.Enables remote control of temperature and humidity verification via mobile phone; Real-time reading of current temperature, humidity values, and chamber operation status; Remote setting of temperature and humidity values; Remote start/stop of the verification chamber. Wi-Fi remote control.

• Automatic Stability Calculation： Features automatic real-time calculation stability. Automatically calculates the current temperature and humidity stability of the chamber, determines if the chamber is stable, allowing metrology calibration work to commence once stable.

• Curve Zooming： Touch screen supports multi-touch; use two fingers to drag and zoom for viewing local and overall curve details (similar to zooming images on a phone); Supports one-touch screenshot to save curve data as an image format for maintenance and data process recording. 

• High Definition Touch Screen： Utilizes a 5-inch high-resolution capacitive screen for clearer display; multi-touch support aligns with user smartphone operation habits; built-in manual for convenient operation lookup.

• Status Indication： Real-time calculation and display of temperature and humidity stability; stability achievement prompt; USB drive insertion detection; Wi-Fi connection status indication.

• Data Logging / Export (USB)： Insert a USB drive to automatically log the chamber's operation data and temperature/humidity curve data into an Excel spreadsheet, and export it to the USB drive with one click.

• Precise & Stable Temperature & Humidity Control： Utilizes high-precision temperature and humidity sensors with PID parameter self-tuning function for fast and stable temperature and humidity control; Built-in multi-point independent temperature compensation function ensures temperature indication error ≤0.1℃ and humidity indication error ≤1.0%RH after compensation, with small full-scale deviation guaranteeing detection accuracy. 

• Multi-segment PID Control： Multi-segment PID control for temperature (better control effect: small overshoot, fast adjustment, low Stability) and multi-segment PID for humidity (effective control). Transition from 40%RH to 60%RH takes only 15 minutes.

• Intelligent Programming Function： Features multi-segment programming function. Frequently used temperature and humidity calibration points can be pre-programmed into the chamber, allowing one-touch start (or timed start) for automatic sequential execution; eliminates the need to repeatedly set points each time. Set once, then calibrate sequentially according to preset values thereafter.
