产品介绍：
美国J-KEM公司为研究jq温度控制器的专业化生产厂家,国内外颇富盛名,在科研领域具有相当高的市场占有率。杭州凯弗克斯实验室设备有限公司为美国J-KEM公司授权的中国大陆地区一级销售代理商。
The Model 270 is designed for uncompromising safety. It is the only temperature controller available with a built-in, independent, backup controller to guard against heating accidents from equipment failure.
The desired temperature is entered into the main temperature controller which regulates temperature is entered into the main temperature controller which regulates heating, and then a high temperature cut-off is entered into the backup limit controller. If the reaction reaches the high temperature limit or a thermocouple breaks, power is turned off to the heater until the controller is manually reset.
Both meters independently monitor the reaction temperature. In the event that one meter fails, the other takes over to prevent a heating accident. J-KEM’s design provides independent, {bfb} redundant control.
Contains J-KEM’s patented power control computer which provides 0.1o C regulation of anything.

New in 2014
USB port and free KEM-Net software. KEM-IO feature
At the heart of J-KEM’s 200-Series controllers is a new, high speed microprocessor that performs 3 functions:
1. Power Regulation J-KEM’s original
power control computer is replaced by a next generation microprocessor. The power control computer is J-KEM’s patented technology that adjusts power to the heater 2048 times per second resulting in 0.1o C regulation.
2. USB Communications PC communications and free KEM-Net software enable remote PC control, GLP/GMP compliant data collection, and multi-temperature ramps built in an Excel-like table.
3. KEM-IO Allows the controller to turn other pieces of equipment On/Off, change the temperature set point, or Start/Stop heating based on external inputs, temperature, or time. See page 37.
Examples:
Turn heating Off when the hood door is opened. Turn it back on when closed.
-
Open a 120 Vac cooling valve if the reaction exotherms to 110C.
-
When the temperature reaches 85C, start a reagent addition pump or stirrer.
