TP7防爆安全温度计(THERMO)
TP7采用RTD设计，密封覆盖的工业质量给用 户提供了一个容易用手套操作的界面。不锈钢外 壳保护电路板和液晶屏，防止遭受水等液体渗透 的影响。
TP7电路板是从高度**、可靠及 成功的TL1实验室温度计一步步演变而来。电源 按钮的主要功能是提供仪器上次按触后约20分钟 的电量， 为了忍受环境以及内在的安全，制造TP9的 材料都是既能防止石化产品的腐蚀，又能够防 爆。外壳由不锈钢制成。探头的构造使用不粘电 缆和不锈钢传感器组件。

PETROLEUMGAUGING THERMOMETER
The TP9 employs the proven RTD design that has been used in the TP7 andTP8 for many years. A sealed industrial quality overlay provides a userinterface that is easy to use with gloves. A stainless steel enclosure protectsthe circuit board and large LCD from penetration by impact, water and reactiveliquids.
The new TP9 circuitboard is an evolutionary step up from our highly accurate, reliable andsuccessful TL1 laboratory thermometer. The Power Button’sprimary function powers the instrument for intervals of about 20 minutes sincethe last button was accessed. The Power Button can also be used to conservepower and clear the memory, or to make adjustment while in calibration mode. Asimple menu operation is displayed by holding the Function Button, andalternately functions to allow adjustments in the calibration mode. Arrows onthe left side of the display show the direction of the temperature reading andwhether stability has been reached. At the user’s discretion stabilized temperaturescan be logged at numerous liquid levels for a running average and laterdisplayed for the user’s documenting purposes. But thisfeature never interferes with simply getting an accurate temperature reading.
To endure the environment and beintrinsically safe, the TP 9 is manufactured of materials, which are bothimmune to petrochemicals and are non-sparking. The enclosure is made ofstainless steel. The probe assembly is constructed using non-stick cable andstainless steel sensor components.
