ASM-802A: 8 channels, each channel can be connected to a small thermocouple plug, thermocouple can be measured to provide accurate cold end compensation. Can transmit maximum 30V, 30mA analog signal. Do not use JOFRACAL software can also work alone, but the need for additional measurement device.

At the same time measuring up to 24 temperature sensors

The system can connect up to 3 ASM, so it can measure up to 24 sensors simultaneously.

Both A and B, can be transmitted or measured 2, 3, 4 wire thermal resistance, with cold end compensation thermocouple, temperature transmitter, temperature switch, voltage, current, resistance and other signals. ASM-801 and ASM-803 also built a 24V loop power supply for the 4-20mA transmitter.

True ohm measurement

ASM-801 and ASM-803 using a true resistance measurement technology, built-in 1 mA constant current source, the two measurement, effectively overcome the measurement loop generated EMF".

Focus on automatic temperature calibration system.

As a worldwide calibration instrument supplier, JOFRA has focused on the research of this product line for more than 25 years, has accumulated a lot of experience.

Simultaneous calibration of 24 temperature measuring elements.

According to their own need for flexible configuration, the same conditions under the calibration of multiple, unattended, save time.

Reserved extended function.

Each scanner 8 channels, the latter need to increase the calibration channel, only on the basis of the existing connection to another scanner can be, without waste of pre investment.

Calibrate any temperature element.

Measurable signals include: 2, 3, 4 wire thermal resistance, thermocouple, temperature transmitter, temperature switch, current, voltage, resistance.

Integrating other JOFRA instruments.

Can be used with any of the JOFRA dry oven, DT11000 digital thermometer, ASC300 multi-function calibration device connected to form an automatic calibration system to enhance the value of existing equipment.

Reference probe input channel.

The first channel of the scanner can be used to measure the reference temperature sensor, the accuracy is as high as 0.026

Reducing the influence of human factors on calibration accuracy.

The entire calibration process does not require any operation.

Easy to generate test reports.

RS232 communication and automatic calibration software as a standard configuration, you can easily constitute a calibration system, output, storage calibration certificate.
