PDY-1低温数字温度计的鉴定会于1983年3月30日至4月1日在兰州进行。全国有关21个单位参加了会议。并对温度计的主要技术指标进行测试和鉴定。会议认为该温度计的各项技术指标均达到和超过了原设计指标。该温度计测温范围宽(+27℃～—269℃),实现了液氦温区的数字化测温,填补了国内的空白。主要指标已接近78年日本同类型的温度计。温度计灵敏度为0.1度。测量精度:其最大误差优于±1度。
PDY-1 low temperature digital thermometer identification will be March 30, 1983 to April 1 in Lanzhou. 21 units nationwide attended the meeting. And the thermometer’s main technical indicators for testing and identification. Meeting that the thermometer of the technical indicators have reached and exceeded the original design specifications. The thermometer temperature range (+27 ℃ ~ -269 ℃), to achieve a digital temperature measurement of liquid helium temperature, to fill the gaps in the country. The main indicators are close to 78 years of Japan’s same type of thermometer. Thermometer sensitivity of 0.1 degrees. Measurement accuracy: its maximum error better than ± 1 degree.
