JY641 four channel high-precision thermometer

Product Overview: The host can be configured with two freely detachable thermocouple/platinum resistance modules, supporting diversified combination forms, and can be freely combined into a four channel high-precision thermometer. Calibration equipment: standard platinum resistors (Pt25, Pt100), industrial platinum resistors (Pt10, Pt100, Pt1000), standard thermocouples (Platinum Rhodium 10 Platinum, Platinum Rhodium 13 Platinum, Platinum Rhodium 30 Platinum Rhodium 6), industrial thermocouples (R, S, B, K, N, J, E, T, WRe3-WRe25, WRe5-WRe26). Main features: * Freely detachable drawer style module, supporting diversified combination forms; *Flexible configuration of thermocouple/platinum resistance module; *Constant current automatic commutation technology can eliminate thermoelectric potential errors at connection points; *Automatically sampling and storing up to 100000 measurement data.

Host Introduction

• Aluminum alloy host, a single host can be configured with up to two modules, freely combined into a four channel high-precision thermometer;

• By inserting a module into any slot, the host can recognize the properties of the module;

• When ordering a host, at least one module must be selected, up to four modules can be selected, or modules can be purchased separately in the future;

• Host size: (210 × 100 × 128) mm;

• Host weight: 2kg.

Module Introduction

• Freely detachable drawer style module, supporting diverse combination forms;

• Choose two JY6A1 platinum resistance modules to combine into a four channel platinum resistance thermometer;

• Choose two JY6B1 thermocouple modules to combine into a four channel thermocouple thermometer;

• At least one module must be selected, and up to four modules can be selected;

• Module size: (130 × 75 × 20) mm;

Feature Overview

• 7-inch color resistive touch screen (155 × 88) mm, dot matrix pixels 800 × 480;

• Measure SPRT and industrial RTD (Pt10, Pt100, Pt1000) for 25 Ω and 100 Ω;

• Measurement standard thermocouples (platinum rhodium 10 platinum, platinum rhodium 13 platinum, platinum rhodium 30 platinum rhodium 6), industrial thermocouples (R, S, B, K, N, J, E, T, WRe3-WRe25, WRe5-WRe26);

• Platinum resistance measurement adopts a four wire connection method, eliminating the influence of wire resistance in SPRT;

• Platinum resistance measurement units can be switched between ℃, ℉, K, and Ω;

• Thermocouple measurement units can be switched between ℃, ℉, K, and mV;

• Constant current automatic commutation technology can eliminate thermoelectric potential errors at connection points;

• The host supports automatic sampling and storage of 100000 measurement data, which can be viewed on the host or downloaded to the computer through a USB interface for saving, editing, or printing;

• By connecting to a computer through a USB interface, unlimited automatic sampling and recording can be performed;

• The platinum resistance temperature measurement module has an automatic calibration function, making temperature measurement more accurate and stable;

• Four sets of sensors can be measured simultaneously, with a measurement cycle of 1 second for thermocouple modules and 2 seconds for platinum resistance modules;

• The refresh cycle for displaying data can be set by oneself: (1-999) seconds;

• 100 sets of sensor calibration parameters can be pre-set;

• The power supply is provided by a dedicated adapter, input: AC 220V ± 10%, 50Hz; output: DC 9.0V/1.5A.
