Datalogger (Pt Sensor Temperature Management)
SK-L753
JAN code : 4974425801442
Calibration : May be available depends on probes
JCSS Accredited Calibration : May be available depends on probes
SK-L753 is a 2-channel temperature logger capable of recording 16000 data. All procedures of configuration, monitoring, downloading, and analysis are finished via PC.
This model adopts a Pt sensor to enable accurate measurements in extreme low temperature as low as 99.9°C.
Furthermore, a Pt sensor connector box attached to the kit enables 4-wire Pt sensors supplied from other manufacturers to be connected with.
A sensor probe must be purchased in addition. Photo describes an example with a probe SK-L753-1 on ch. 1 and SK-L753-2 on ch. 2.
Instruction manual
Feature
■ IP65 dustproof/waterproof
SK-L753 conforms IP65 if the following conditions are met;
- Either one or two of probes SK-L753-2, SK-L753-2 are connected
- AC adapter is not used
■ AC/DC input compatible
This product functions well with batteries, however, it is recommended to use AC inlets for measurement in a long duration.
When the AC adapter is connected while the batteries are installed, power is supplied from AC inlet preferentially, and it switches to using the batteries in case of a problem such as blackouts.
■ Fourteen different logging intervals
Available logging intervals: 1, 2, 5, 10, 15, 30 seconds and 1, 2, 5, 10, 15, 30, 60, 90 minutes.
■ AC/DC input compatible
This product functions well with batteries, however, it is recommended to use AC inlets for measurement in a long duration.
When the AC adapter is connected while the batteries are installed, power is supplied from AC inlet preferentially, and it switches to using the batteries in case of a problem such as blackouts.
■ Memorizes up to 16000 data
Available to record data for 4 hours with a logging interval of 1 second and for as long as 2 years and 9 months with an interval of 90 minutes.
* Maximum number of data x logging interval = maximum logging time. E.g., 16000 x 5 sec. = 22.2 hours
■ Scheduled logging
Available to preset the time to start logging automatically.
■ Data can be copied to PC and micro SD
Logged data can not only be downloaded to a PC but also be copied to a micro SD card (sold separately). Copying can be done even when logging.
■ Four logging mode options selectable
- Once (default)
Keeps logging until the memory becomes full. Stops logging when 16000 data are recorded.
- Repeatedly (overwriting)
Overwrites the existing data from the beginning once the 16000 data are recorded. Ideal for the case you only need to store data of the latest period.
- Ends at (limited amount)
Stops logging when the number of data reaches the limit you set. Ideal for limiting the amount of data to be collected.
- By page (partitioning)
Partition the memory into four blocks, each having the capacity to store 4000 data. Once you stop logging and restart it the data is stored in the next block, thus it is convenient to sort and manage the data of different time or locations.
■ No data loss even if battery runs out
Data is securely stored in the memory to avoid losing even if there is a power failure.
■ Key lock function
Prevents misoperation while in logging or in standby for preset start.
■ Warning display for upper and lower thresholds
An alarm light is lit and Hi/Lo indicator blinks if the temperature exceeds or falls below the preset thresholds. The light and the indicator turn off when the measured value falls back within the range of the set values.
■ ID number for each device
A 6-digit ID number can be set for easy identification when multiple loggers are used.
Description
■ Features of attached analysis software
Main window
Configures the settings for the main unit, downloads measured data, and analyzes it.
- Both the logged data in the main unit and the data copied to a micro SD (sold separately) can be downloaded.
- Up to ten units can be controlled using a USB hub.
- Imported data can be zoomed in and out, plotted, exported, printed, and analyzed in various ways such as partial analysis and integral analysis.
- Exporting the data in CSV format enables other spreadsheet software to edit it.
Real-time monitoring
Displays measured data in real-time chart when the main unit and the PC are connected with a communication cable.
- Updates current value, maximum, minimum, average, WBGT value, and alarm information in real time.
- Up to ten units can be monitored simultaneously using a USB hub if all units are the same model or a combination of SK-L751 and SK-L753.
- Graph plotting and exporting are available during monitoring.
- Alarm for Hi/Lo thresholds, WBGT, and battery shortage are available. It has also an option to send email to a preset address when alarm is activated.
* Windows PC only
