Product Details

The pH-HR is a small three channel high resolution (12 bit) pH and Temperature data logger housed in a rugged 304 stainless steel case. The logger connects to an external pH probe and also has the option of connecting to an external RTD Pt100 temperature probe to allow temperature compensation of the pH reading. Many pH probes have a built in RTD Pt100 temperature sensor for convenient connection.

The pH-HR logger also has an internal temperature sensor for convenient logging of ambient temperature if desired. Logging can be configured to: start on time, immediate start, stop when full, loop around (overwrite oldest data).

Features

Over 500,000 samples can be logged (when logging pH only)!
pH and Temperature can be set to any combination of Point, Average, Maximum & Minimum readings
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”, started at a given time in the future or on a condition (e.g. pH > 6.2pH)
The data from any logger that records Temperature can now be processed, by the Omni7 software, to give daily, weekly and monthly accumulated Grow Degree Day reports for a wide range of horticultural crops

A DLC3USB [USB] download cable (2m) is required to connect the pH-HR to a computer.

	Long term stability	±0.1ºC
Logger:	Working Temperature	-30ºC 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 pH only 261,120 samples logging pH and Temperature 362 days with 1 min logging interval, pH only 4.9 years with 5 min logging interval, pH only
	Alarms	Two independent Alarms Triggered on any combination of six user configurable Alarm Conditions Both alarm can be configured to send SMS messages Conditions can be setup to reset alarms Alarms can be visually checked using the Omni7 software
	Start modes	Start immediately / Start on date/time / Start on condition (e.g. pH > 6.2pH)
	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 - Maximum reading - Minimum reading - Average 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 aboveUsing the logger in temperatures below -5°C (23°F) will reduce battery lifeOne 7.2V lithium battery; User ReplaceableThe data is retained in the case of battery failureBattery Status Monitor in Omni7 software
	Download time	9min 30sec for Full Logger
	Case material	304 Stainless tube
	Screw on end cap	Plated brass
	Weight	148g
	Size	20mm diameter X 182 mm long
	Temperature Compensation	Temperature compensation is performed within the logger so temperature data does not have to be logged if it is not required
	Calibration	The pH input is calibrated in the factory at 25ºC with a traceable calibrated voltage source. Temperature compensation is then checked at 0ºC, 50ºC and 100ºC.
