Tesa Micro-Hite an All-Purpose Metrology Height Gauge
CASE STUDY TESA MICRO-HITE AN ALL-PURPOSE METROLOGY HEIGHT GAUGE TESA’s MICRO-HITE electronic vertical height gauge is wi- dely used for measuring precision parts in workshops or gauge rooms. This battery-powered instrument elimina- tes the need for cables and glides on its own air cushion on a surface plate. It can measure internal, external, height, depth and step dimensions of geometric part fea- tures having either a flat, parallel or cylindrical surface. With the Power Panel plus M, the MICRO-HITE can mea- sure in single or two coordinate measurements as well as determine bore positions, both in polar and rectangular coordinates. The MICRO-HITE comes with many accessories, including a TESA IG13 probe for measuring perpendicularity and straightness errors. The latest generation MicroHite plus M versions, equip- ped with a rotary power control, combine the speed of a manual height gauge with the precision of a motorised one. The MICRO-HITE is, thus, the most versatile and accurate height gauge in its class.

Metric System Units of Length
Math 0300 METRIC SYSTEM UNITS OF LENGTH Þ To convert units of length in the metric system of measurement The basic unit of length in the metric system is the meter. All units of length in the metric system are derived from the meter. The prefix “centi-“means one hundredth. 1 centimeter=1 one-hundredth of a meter kilo- = 1000 1 kilometer (km) = 1000 meters (m) hecto- = 100 1 hectometer (hm) = 100 m deca- = 10 1 decameter (dam) = 10 m 1 meter (m) = 1 m deci- = 0.1 1 decimeter (dm) = 0.1 m centi- = 0.01 1 centimeter (cm) = 0.01 m milli- = 0.001 1 millimeter (mm) = 0.001 m Conversion between units of length in the metric system involves moving the decimal point to the right or to the left. Listing the units in order from largest to smallest will indicate how many places to move the decimal point and in which direction. Example 1: To convert 4200 cm to meters, write the units in order from largest to smallest. km hm dam m dm cm mm Converting cm to m requires moving 4 2 . 0 0 2 positions to the left. Move the decimal point the same number of places and in the same direction (to the left). So 4200 cm = 42.00 m A metric measurement involving two units is customarily written in terms of one unit. Convert the smaller unit to the larger unit and then add. Example 2: To convert 8 km 32 m to kilometers First convert 32 m to kilometers. km hm dam m dm cm mm Converting m to km requires moving 0 . -
Units and Conversions
Units and Conversions This unit of the Metrology Fundamentals series was developed by the Mitutoyo Institute of Metrology, the educational department within Mitutoyo America Corporation. The Mitutoyo Institute of Metrology provides educational courses and free on-demand resources across a wide variety of measurement related topics including basic inspection techniques, principles of dimensional metrology, calibration methods, and GD&T. For more information on the educational opportunities available from Mitutoyo America Corporation, visit us at www.mitutoyo.com/education. This technical bulletin addresses an important aspect of the language of measurement – the units used when reporting or discussing measured values. The dimensioning and tolerancing practices used on engineering drawings and related product specifications use either decimal inch (in) or millimeter (mm) units. Dimensional measurements are therefore usually reported in either of these units, but there are a number of variations and conversions that must be understood. Measurement accuracy, equipment specifications, measured deviations, and errors are typically very small numbers, and therefore a more practical spoken language of units has grown out of manufacturing and precision measurement practice. Metric System In the metric system (SI or International System of Units), the fundamental unit of length is the meter (m). Engineering drawings and measurement systems use the millimeter (mm), which is one thousandths of a meter (1 mm = 0.001 m). In general practice, however, the common spoken unit is the “micron”, which is slang for the micrometer (m), one millionth of a meter (1 m = 0.001 mm = 0.000001 m). In more rare cases, the nanometer (nm) is used, which is one billionth of a meter. -

We are glad that you are interested in our products. The foundations of KOBA were laid more than 70 years ago and at the beginning the manufacture of gauge blocks was the major line. At that time gauge blocks were made out of steel. Later carbide and ceramic were added. Furthermore we manufacture accessories in order to extend the application of our gauge blocks. In order to complete the product range we started the manufacture of gauges. It was in 1979 when KOLB & BAUMANN got accredited by the PTB as the 8th DKD-calibration laboratory in Germany. This accreditation comprises the measured value "length” up to 1000 mm. Besides, KOBA is accredited laboratory for gauges and other measuring instruments. KOBA supplies world-wide into more than 70 countries and is also supplier for gauge blocks and calibration masters to various National Physical Laboratories. Our world-wide customers trust in KOBA-gauge blocks and gauges as a high- grade German quality product. Being a German family-based company we will do all efforts to keep the confidence in our products. -
Consultative Committee for Amount of Substance; Metrology in Chemistry and Biology CCQM Working Group on Isotope Ratios (IRWG) S
Consultative Committee for Amount of Substance; Metrology in Chemistry and Biology CCQM Working Group on Isotope Ratios (IRWG) Strategy for Rolling Programme Development (2021-2030) 1. EXECUTIVE SUMMARY In April 2017, the Consultative Committee for Amount of Substance; Metrology in Chemistry and Biology (CCQM) established a task group to study the metrological state of isotope ratio measurements and to formulate recommendations to the Consultative Committee (CC) regarding potential engagement in this field. In April 2018 the Isotope Ratio Working Group (IRWG) was established by the CCQM based on the recommendation of the task group. The main focus of the IRWG is on the stable isotope ratio measurement science activities needed to improve measurement comparability to advance the science of isotope ratio measurement among National Metrology Institutes (NMIs) and Designated Institutes (DIs) focused on serving stake holder isotope ratio measurement needs. During the current five-year mandate, it is expected that the IRWG will make significant advances in: i. delta scale definition, ii. measurement comparability of relative isotope ratio measurements, iii. comparable measurement capabilities for C and N isotope ratio measurement; and iv. the understanding of calibration modalities used in metal isotope ratio characterization. 2. SCIENTIFIC, ECONOMIC AND SOCIAL CHALLENGES Isotopes have long been recognized as markers for a wide variety of molecular processes. Indeed, applications where isotope ratios are used provide scientific, economic, and social value. Early applications of isotope measurements were recognized with the 1943 Nobel Prize for Chemistry which included the determination of the water content in the human body, determination of solubility of various low-solubility salts, and development of the isotope dilution method which has since become the cornerstone of analytical chemistry. -
