Product Details

Description

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 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

Technical Specs

TYPE		THT-LCD
Humidity Sensor:	Probe Plug	The probe is connected to a socket on the end plate at the top of the logger The probe cable is 1.5 metres long
HT11-Probe	Sensirion SHT11 Digital humidity sensor
	Long-term stability	Fully calibrated by Sensirion
	Response time	4 seconds Range 0%~100%
	Accuracy	±3.0%RH from 20% to 80% Accuracy ±5%RH from 0% to 20% and 80% to 100%
	Resolution	0.1%RH Digital temperature sensor accuracy ±0.4ºC @ 25ºC
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).
Dew Point:	Sensor Type	The Dew Point is calculated from the current Relative Humidity and Temperature
	Accuracy	±2ºC (this is determined by the ±3.0%RH accuracy of the humidity sensor
	Resolution	0.1ºC
Internal Temperature:	Sensor Type	Thermister
	Linear accuracy over range	±0.3ºC (0ºC to 70ºC)
	Repeatability	±0.1ºC
	Long term stability	±0.1ºC
Logger:	Working Temperature	-20ºC to +70ºC
	Storage Temperature	-30ºC to +70ºC
	Sampling Rate	1 second minimum, 10 hours maximum; in 1 second intervals Storage capacity 522,240 samples logging Relative Humidity only 362 days with 1 min logging interval (Relative Humidity only) 4.9 years with 5 min logging interval (Relative Humidity only) 174,080 samples logging Relative Humidity Dew Point and Temperature
	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
	Download time	9 minutes 30 seconds for Full Logger
	Case material	ABS Plastic
	IP Rating	40
	Weight	185g
	Size	130mm x 80mm x 30mm
Communication Connector The HT-LCD has a 8 pin Mini-DIN female socket
Pinout	Pin 1 Common	Pin 2 RS232 RX (out of logger)
	Pin 3 RS232 TX (into logger)	Pin 4 RS232 CTS (out of logger)
	Pin 5 RS232 RTS (into logger)	Pin 6 Alarm 1 Open Collector Output
	Pin 7 Alarm 2 Open Collector Output	Pin 8 Power 9 to 16Vdc
