采用成熟的tp7-c RTD的设计已被用于在TP 7和TP 8多年。一个密封的工业质量覆盖提供了一个用户界面，易于使用的手套。聚丙烯共混物外壳保护电路板和大液晶显示器从渗透的影响，水和反应性液体。

新的TP 7C电路板是一个进化步骤由我们高度准确、可靠和成功的TL1实验室温度计。电源按钮的主要功能是为20分钟左右的时间间隔的仪器，因为后一个按钮被访问。电源按钮也可用于节省电力和清除内存，或作出调整，而在校准模式。一个简单的菜单操作是通过按住功能键来显示的，并且在校准模式下允许调整。显示器左侧的箭头显示温度读数的方向和是否已达到稳定。在用户的自由裁量权的温度可以记录在许多液体的水平，为一个运行的平均值，并为用户记录的目的后显示。但这种功能永远不会干扰简单地得到一个的温度读数。

忍受环境和本质安全，TP 7C是制造材料，这两者都是免疫石化和无火花。外壳由聚丙烯共混物制成。使用无粘电缆和不锈钢传感器组件构造的探针组件。

The TP7-C employs the proven RTD design that has been used in the TP 7 and TP 8 for many years. A sealed industrial quality overlay provides a user interface that is easy to use with gloves. A polypropylene blend enclosure protects the circuit board and large LCD from penetration by impact, water and reactive liquids.

The new TP 7-C circuit board is an evolutionary step up from our highly accurate, reliable and successful TL1 laboratory thermometer. The Power Button’s primary function powers the instrument for intervals of about 20 minutes since the last button was accessed. The Power Button can also be used to conserve power and clear the memory, or to make adjustment while in calibration mode. A simple menu operation is displayed by holding the Function Button, and alternately functions to allow adjustments in the calibration mode. Arrows on the left side of the display show the direction of the temperature reading and whether stability has been reached. At the user’s discretion stabilized temperatures can be logged at numerous liquid levels for a running average and later displayed for the user’s documenting purposes. But this feature never interferes with simply getting an accurate temperature reading.

To endure the environment and be intrinsically safe, the TP 7-C is manufactured of materials, which are both immune to petrochemicals and are non-sparking. The enclosure is made of a polypropylene blend. The probe assembly is constructed using non-stick cable and stainless steel sensor components.

Operational Attributes:

Easily replaceable AA Batteries, provides an estimated *200 hours operation.

Circuit logic automatically indicates low battery condition, automatically shuts off after twenty minutes, shows temperature trend and stabilization, displays error codes for failure determination.

The low power backlight for night operation is photo sensor controlled for convenience and battery conservation.

In nighttime conditions the backlight illuminates the display.

Celsius or Fahrenheit units with C/F indication can be easily selected from the Function Button.

User Manual explains intuitive calibration procedure that can be done through the external faceplate buttons.
