Measure surface temperature fast and avoid cross-contamination. Use the retractable RTD puncture probe for insertion temperature reading. During temperature checks, the green and red lights indicate if the temperature is within the HACCP safe zone. 快速测量表面温度,防止交叉感染。使用可更换的RTD热面电阻温度探头来测量食品中心的温度。测温过程中,红灯和绿灯会提示温度是否在HACCP安全温度区域内。
