The THT-LCD is a handheld humidity data logger with an external humidity and temperature probe and a liquid crystal display.
Both Relative Humidity and Dew Point can be displayed and logged.
The HT11-Probe uses a Sensirion SHT11 digital humidity sensor giving ±3.0%RH accuracy from 20%RH to 80%RH.
The probe is connected to a socket on the end plate at the top of the logger.
The probe cable is 1.5 metres in length. This logger is designed for indoor use (IP 40). For outdoor applications, we recommend mounting the THT-LCD in a Seahorse Logger Enclosure.
THT-LCD – Humidity and Dual Temperature Data Logger
Three Channel High Resolution (16 bit) Humidity & Temperature Data Logger with LCD Display.
THT-LCD Overview
- Temperature can be set to any combination of Point, Average, Maximum & Minimum readings.
- The data from any logger that records Temperature and Relative Humidity can be processed, by the Omni7 software, to add Absolute Humidity and/or Dew Point readings to the data.
- The battery voltage of the logger can be logged if required.
- The logger can be run in either “Stop when memory is Full”, “Loop Around” mode or set to stop at a future time.
- The logger can be started “Now” or started at a given time in the future

| Filter | The sensor is covered in a Sensirion SF1 Filter cap. The filter cap provides protection against water, dust and other contaminants for the humidity and temperature sensor. The filter cap consists of a single piece of polypropylene including a filter membrane. The filter provides filtration efficiency of 99.99% of all 0.1µm particles and has an optimised response time of typically 30s (1/e (63%) slowly moving air). | |

| Alarms | Two independent Alarms Triggered on any combination of six user configurable Alarm Conditions Both alarms can be configured to send SMS messages if connected to a cell modem Two Open Collector Alarm Outputs Alarms can be visually checked on the LCD Display or by using the Omni7 software |
|
| Start modes | Start immediately; Start on date/time; Start on Condition (e.g. Humidity <30%RH); Start on trigger (push button on logger) |
|
| Stop modes | Stop when memory is full; Stop on date/time; Loop around (continues logging) | |
| Logging modes | Each channel can be set to log any combination of: -Point readings, -Average reading, -Maximum reading, -Minimum reading |
|
| Warning: When using the Average, Maximum or Minimum reading(s), the logger reads the attached sensor(s) every second. This will reduce battery life. | ||
| Battery | One to Five year life depending on usage as above Using the logger in temperatures below -5°C (23°F) will reduce battery life User Replaceable; Two 3.6 volts Lithium AA cells The data is retained in the case of battery failure Battery Status Monitor on LCD display and in Omni7 software |
