Calibration laboratories - Import export

Over the last few years, we at EP-E have designed and introduced a series of primary standards for gases, designed for use in calibration laboratories. As a technology partner of the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, our solutions are based on the highest standards. The EP gas bell plungers generate a volume flow which is traceable to the SI units length and time. The pistons are driven by a stepper motor via a spindle. In the initial state one piston is fully retracted and the other fully extended. The volume flow can be set with high precision via the piston cross section and the travel speed. At the end of the calibration process, both pistons are in the opposite position to the initial position. The calibration device is preferably operated with air, which can be supplied with up to 6 bar. The EP gas bell pistons convince by highest measuring accuracy up to 0.15% (k=2).

The precision RTD simulator is used where measuring instruments or controlling means with high precision must be examined or calibrated. The simulator is suitable for calibration laboratory and service centers which need a computer-controlled resistance decade for the automation of calibration procedures. All standard platinum and nickel RTD can be simulated with very high accuracy according to scales ITS 90 or IPTS 68. Temperature regulators, transducers etc. often supply a pulsed signal current in order to reduce the self-heating of the RTD. Devices with electronic simulation of RTD are therefore inclined to swinging and do not function with this application. Features: — Simulation of Pt100, Pt200, Pt500, Pt1000, Ni100 and Ni1000 sensors — Accuracy 0.02 °C — Temperature scales ITS 90, IPTS 68 — Real Ohm simulation — Control manually or remotely via RS232/IEEE488/USB Converter

The 0.02 class calibration resistors excel in their modern design and small mechanical dimensions. Their ruggedness also ensures a long life. Calibration resistors of the 1240 series are used wherever very constant operating standards are required. Typical main areas of application therefore include: — When normal resistors prove to be too large scale — For test and calibration of resistance measurement devices — For tests on electrical temperature measuring equipment — For laboratory setup of a Wheatstone bridge — As shunt resistor for accurate current measurement — As part of standard equipment in research laboratories — For a large part of measurements in calibration laboratory. Features: — Range 10 μΩ ... 100 kΩ — Low capacitance and low inductance design — Suitable for direct current and technical frequencies — High stability < ± 0.01 % over years

Preset Torque Screwdriver Sturtevant Richmont PM-Series Preset Torque Screwdrivers are ideal for any application where 1. high repeatability for low torque is needed, 2. excellent durability and versatility is needed. These needs are common in high-precision assembly operations and for maintenance tool kits for electronic and electro-mechanical products. The operator cannot overtorque. A clutch releases automatically when desired torque has been achieved. The anti-backlash design enhances the repeatability. PM torque screwdrivers are incredibly durable. Many owners experience a service life of 15+ years. Key Features: - Bi-directional accuracy of ± 6% i.v. (20-100% of capacity) - Meets or exceeds ASME B107.300-2010 & EN ISO 6789 - Anti-backlash design - Short dwell designed to prevent repetitive motion injuries - 1/4 hex drive (C 6.3) Can be ordered preset from factory with certificate of calibration from SR's ISO/IEC 17025 Accredited Calibration Laboratory.

We offer LED technologies for existing applications. With our modular concept, combined with our calibration laboratory and in-house production we offer decisive development advantages. POSSIBLE REASONS FOR CUSOMIZED UV-LED: The system already exists. Standard products can’t be installed due to limited space. Irradiation from one direction is not sufficient The determination of irradiation wavelength has not yet taken place You are looking for a competent and independent partner YOUR ADVANTAGES WITH OPSYTEC UV-LED CUSTOMIZED SOLUTION: Development and production from a single source Ideal for small batches, tests and prototypes Wavelength 275 nm, 365 nm, 385 nm, 395 nm and 405 nm available Further wavelengths are possible Suitable sensor?

Traceable calibration of testing machines and instruments is essential for industrial quality control. Calibration certificates are a compelling proof of test equipment inspection for the standards DIN EN ISO 9000ff and DIN EN ISO / IEC 17025. The time intervals for the calibration will depend on the applicable standard, but should normally not exceed 12 months. Attention should also be paid to the rules for local changes or repairs. Take advantage of our many years of experience in the field of calibration. TesT is accredited by the German Calibration Service (DAkkS, member of WECC) for on-site calibration of testing machines, for the quantities force, length and torque as well as a permanent laboratory for calibration of compressive force transducers

To ensure that an instrument provides accurate measurements, regular calibrations are necessary. Calibration means to operate a target-performance comparision using a measuring instrument and a traceable reference. Calibration of instruments is essential in every area where sensitive measurement technology is used, e.g. in the manufacturing of sensors. It is the only way to guarantee quality standards and prevent defects arising in processes and products from the outset. For companies wanting to attain ISO 9001 certification, regular calibration of testing equipment is a requirement. halstrup-walcher has been accredited by the German calibration service DKD and Deutsche Akkreditierungsstelle GmbH (DAkkS) as a calibration laboratory in accordance with DIN EN ISO / IEC 17025 since 1999 – among other things for calibration of pressure measurements.
