Product Description:
JK-8C多路温度测试仪配备大屏幕液晶Show屏,Usb flash drive保存接口,可方便测量Show和保存温度数据,是一种适用于多点同时实时监控跟踪的仪器.

The high voltage semiconductor relay is used as the scanning of switching input signal, which realizes the high-speed scanning and eliminates the noise and service life problems caused by the traditional relay. Can set the upper and lower limit temperature of each channel,

限声音报警.大屏幕液晶Show,可同时Show多路温度值具备Usb flash drive接口,插入Usb flash drive可海量保存温度记录数据.

Especially for oven, sterilization cabinet, lamps, household appliances, motors, electric heating appliances, temperature controllers, transformers, heat protectors and other industries of manufacturers and quality inspection departments to detect the multi-point temperature field. Energy-saving light bulbs,

电子镇流器Inside的三极管、扼流圈、磁环、电容等元件的温度同时进行带电实时监控,由电脑将整个温升变化过程全部以曲线方式记录下来,便于分析、改进、

It ys a great role in improving the reliability of energy-saving lamps and electronic ballasts

Instrument features:
1: multi-channel temperature test software and instrument use, the computer automatically receive test data, temperature record, storage and curve disy, and print forms and curves

2: JK-XC可以设定参数选用1~64路任意路测量,配接不同的热电偶满足不同的温度Measuring range;大屏幕液晶Show,各路温度参数和温度曲线Show,（各路温度值全部Show及一路温度报警Channel）

The computer serial communication is directly connected to the computer to collect data. The software is specially designed for the user's special requirements of multi-channel temperature at the same time. It can measure a sample or multiple different samples at the same time, or record the name of multiple test sites, and also can measure a sample at different inches

Or multiple different samples, the temperature can be set 曲线颜色,There is设计简繁体中文和英文版本,适合多种不同测试用途需求

3: cold end ambient temperature: measuring range of 0 ~ 60℃

4:本机还带There is日期和时间设定具There is定点、巡检功能;巡检时间可设定：1秒～255秒,测量时间间隔可以设定（不少于1秒）;

5: The temperature unit Celsius (C) Fahrenheit (F) can be automatically converted; An instrument can choose T, J and K thermocouple

6:测试Channel可以任意设定,满足测量的要求和速度;

7:状态栏实时Show设定参数;各Channel不均匀度：0.5℃

8:热电偶探头可接触不过AC250V的带电物体进行测量而不会损坏仪表;热电偶探头可接触发热体There is相关极限,订货时须提出测量温度范围,以提供相应防护材料

JK-XC multichannel temperature tester is suitable for lamps, household appliances, motors, electric heating appliances, temperature controllers, transformers, heat protectors and other industries of manufacturers and quality inspection departments on the spot of multi-point temperature detection

Note:

①表中的T J K为探头的Model number,温度范围分别为:

J-mark -100 ~ 750

K marks range from 100 to 1200

T index is -100 to 400

②曲线：指仪器不要软件在液晶屏幕中实时Show温度曲线并储存在仪器Inside,可以通过Communication interface将曲线保存在电脑中.

③数据：指仪器不要软件将温度值以序号、路数、采集时间及对应的温度值储存在仪器中,可以通过Communication interface将数据保存在电脑中.

仪器出厂每路均配There is2米长的测温(耐温250℃)导线,如需加长则按10元/米计算！配的是K型线为防止突然断电影响测试,建议配UPS电源
