Rheology
Rheology is the study of flow and deformation of materials. Deformation and flow are referred to as strain or strain rate, respectively, and indicate the distance over which a body moves under the influence of an external force, or stress. For this reason, rheology is also considered to be the study of stress-strain relationships in materials.

Two Axis Differential Interferometer
10721A
The Keysight 10721A Two Axis Differential Interferometer, when used in multiple axis applications, simultaneously makes two differential measurements linear and angular (yaw) displacement. Both measurements reference external mirror mounted to an object such as a column or inspection tool. The 10721A provides high immunity to unwanted interferometer displacement, such as thermal expansion. It is a modular, compact design with monolithic optics for maximized mechanical stability. Use of a small 3 mm beam helps decrease Abb offset error. The 10721A is similar to the 10719A Single Axis Differential Interferometer, except that it provides an additional measurement axis.

Bore Gauge
BG10
Aeronautical & General Instruments Ltd.
The BG10 Gun Barrel Bore Gauge System is an electro-mechanical measuring device that was originally introduced into service by the RAF for the high-speed measurement of aircraft cannons, to ensure minimum operational aircraft turnaround time. Measurements are taken at 16 pre-determined positions along each bore, which are then compared to pre-stored warning and rejection criteria. The actual measurements taken are displayed to the Operator on an LCD display and the measurements stored for future reference. The system will automatically provide a visual indication on the Hand Held Unit whether the barrel was acceptable, close to tolerance or rejected – all this to be undertaken in less than five minutes!

Sound Level Indicators
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.An important attribute to consider when searching for a suitable sound level meter is its type or class. The type or class of a sound level meter defines the device's accuracy as per American National Standards Institute (ANSI) or International Electrotechnical Commission (IEC) guidelines. Typically, "type" is the grade according to the ANSI S1.4 standard, whereas "class" is the grade according to the IEC 61672 standard. There are two types or classes assigned to sound level meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 sound level meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used. PCE sound level meter products are lightweight, easy-to-use and manufactured in accordance with the highest industrial standards.
