Power Quality Analyzer
PQM-711
PQM-711 power quality analyzer is an advanced product for wide type of measurements, analysis and recording of network parameters 50/60 Hz and the power quality diagnostic according to European standard EN 50160. PQM-711 is an innovative model with a wireless communication Wi-Fi , which allows for automatic pairing with the included tablet, with a large 10" touch screen. Tablet allows full operating of the analyzer, live data preview and the reading and analysis of data stored in the internal memory. With this solution, the PQM-711 is an unique device that combines the advantages of the analyzer with built-in display and typical portable analyzers (known as Black Boxes).With the tablet you can very fast checked the device under test. On the other hand, you can leave the analyzer module for multi-measurements as a typical logger without display. You can very fast diagnose the machine under test using the tablet. On the other hand, you can leave the analyzer module itself for many days measurement as a typical logger without display. PQM-711 has a transient registration with a maximum sampling rate of 10 MHz (rapid changes in voltage) and control signals. The minimum duration of the registered transient is 650 ns.

Produce Quality Meter
F-750
The F-750 Handheld Brix & Dry Matter Meter uses near-infrared (NIR) spectroscopy to estimate quality metrics such as dry matter, Total Soluble Solids (TSS or brix), titratable acidity, and color. Working like a high-powered flashlight, the F-750 sends particles of light into a commodity, then measures the NIR light interactance with molecular components inside of the commodity to quantify user-selected traits. The F-750 has a wide range of applications, from determining optimal harvest timing by assessing fruit maturity, to providing an objective analysis of produce quality of fruit in packing houses and upon import. The F-750 is a handheld, fully integrated system, allowing users to operate it out in the orchard or inside the QA lab. Its simple, intuitive user interface makes it easy for anyone to use, while its model building software makes it customizable and versatile.

Carbon / Water Analyzer
CW‑800M
ELTRA’s CW-800M analyzer is designed for fractional analysis of carbon and water in one single operation. It is based on the proven technology of the CW-800 but has a modified furnace which allows fast adjustment of the temperature in the furnace. Different fractions of carbon and water of the sample are analyzed by applying different furnace temperatures. ELTRA’s CW-800M analyzer is designed for the precise, simultaneous determination of carbon (released as CO2) and water in lime, gypsum and cement from trace level up to 100 % (depending on sample weight). Other sample materials include ores, soil, minerals, slags and waste.

Water Samplers: Water Samplers
A water sampler is often used in conjunction with a CTD. The water sampler collects 1 or more actual samples of water for analysis in the lab after recovery of the package. The water samples can be used to verify the accuracy of data measured by the instruments on the package, and/or to provide additional information that cannot be measured with an instrument in the field. Sea-Bird water samplers can be controlled (i.e., bottles closed) from deck via a Sea-Bird deck unit and software, or can be pre-programmed to close bottles at desired depths. Sea-Bird manufactures two water samplers: the SBE 32 Carousel (up to 36 bottles, 1.7 - 30 liters, available in regular, compact, and sub-compact sizes, for depths to 10,500 m) and the SBE 55 ECO (small, 3- or 6-bottle sampler for depths to 600 meters).

PQM-703
Power quality analyzer PQM- 703 is a technically advanced product that allows for comprehensive measurements of the quality of electricity , analysis and recording of power network parameters, for frequencies 50/60 Hz in accordance with European standard EN 50160. PQM -703 is another representative of a well, known family of analyzers line PQM- 70x . In relation to the PQM -702 has new functions like recording of transients with max. sampling frequency 10 MHz (rapid changes in voltage) and control signals. Minimal transient capturing time is 650 ns. It is intended for a very wide range of users who need to control the quality of power with a mobile device , which fulfills the requirements of a multi-sheet standard IEC 61000 for class A analyzers. This applies to measurement accuracy, measurement methods, and synchronization of time with a standard signal. The last condition is met with a built-in GPS module with an internal antenna. If the analyzer is installed inside, it is possible to use an additional antenna with a 10m-long wire. If the antenna is situated outside, GPS signal will be attainable without any problems and used for the synchronization of an internal clock.

Testing Released Water Vapor
Humiditest™ Complete System
The James Instruments Humitest System allows the concrete practitioner to monitor and ensure that a new structure is dry enough to proceed with the next phase of construction. This is especially critical for concrete structures requiring a coating, carpeting or similar floor or covering treatment. Installing such treatments before the concrete is sufficiently dry will typically cause expensive failures in the covering treatment. The only accurate way to ensure that the concrete is sufficiently dry enough to safely avoid expensive re-work is via a bore hole humidity test system, such as the Humitest System
