玻璃毛細管黏度計 (Glass Capillary Viscometers)本法用以測定透明與不透明產品的黏度，它是在已知的溫度下，利用液體本身的重力流動性(gravity-flow)來測定一定體積的液體通過經校正后的毛細玻璃管黏度計所需的時間。根據所測出的動力黏度可計算出公制黏度或優良黏度(dynamic viscosity)。

本法用以測定透明與不透明產品的黏度，它是在已知的溫度下，利用液體本身的重力流動性(gravity-flow)來測定一定體積的液體通過經校正后的毛細玻璃管黏度計所需的時間。根據所測出的動力黏度可計算出公制黏度或優良黏度(dynamic viscosity)。
方法概要：
取一定體積的液體在嚴格的溫度與固定的液面高度的控制下，使其流經毛細管黏度計而計算其流經時間。根據流經時間與黏度計的校正常數的乘積即可得動力黏度。

儀器：
黏度計：校正過后的玻璃毛細管，其所測得的黏度能符合于所要求的檢測精度和重復性要求。
黏度計支架：能將黏度計在恒溫槽中架持穩固，且能使其垂直豎立。
黏度計恒溫槽：內盛裝透明液體，能使樣品于黏度計內較液面低20mm以下，或高于槽底20mm以上，能保持槽內溫度的變動于15至100℃間低于±0.02℃的變化，在此溫度范圍以外，亦不超過±0.05℃的溫度變化。
測溫表/溫度計：檢驗動力黏度計的溫度計內盛有適當的液體，使之能符合溫度范圍，溫度計使用前均需校正，校正后準確度在±0.02℃，若其它測溫器有上述的精確度時亦可采用。
計時器：電子秒表或發條裝置的定時器均可使用，但其刻度至少在0.1秒，其測定200秒至900秒的誤差在±0.07%以內。

MTMDP-3L多量程扭矩試驗儀平頂山南陽許昌漯河

產品描述：

The MTM Series of torque transducer are designed to provide an economical way to measure and calibrate multiple torque tools. The MTMDP models (MTMDP-2S pictured) include an integrated display for a fully integrated tester.

Historically, transducers had to be purchased individually and connected to a display via a switch box or a group of cables. With the MTM series, up to 4 transducers can integrated in one compact housing.

The small footprint also allows for a clean, well-organized work space. This helps eliminate the endless searching for cables, adapters, and other accessories that may be needed.

Features such as independent CW and CCW calibration, multi-point linearization, metrology grade transducer shafts, and overload protection to 200% of full scale are standard. All of the above translate to a better product for you at an unbeatable price.

* MTMDP-2 coupled with an MTM-4.

Features

Available with 2, 3 or 4 torque transducers

Selectable units of: Ft-lb, IN-lb, IN-oz, KGF-m, KGF-cm, GF-cm, CN-m, N-m
