Non-Intrusive voice Quality Analyzer
NIQA
-
The most known methods for quality evaluation of voice transmission systems were developed by Telecommunication Standardization Sector of International Telecommunications Union (ITU-T) in the middle of 90-s. Results of this work are presented in Recommendation P.800 (P.830) «Methods for subjective determination of transmission quality» [1, 2]. This document describes conditions for voice quality testing, audio contents, scoring and methods to evaluate results. Typically “Methods for subjective determination of transmission quality” are used to obtain mean subjective quality score according to five-digit scale (Mean Opinion Score – MOS).

Blood Ionized Calcium Pocket Water Quality Meters
LAQUAtwin Ca-11C
-
Milk fever, or Sub Clinical Hypocalcemia (SCH) is a significant problem with dairy cows. Total calcium levels in the cows’ blood drop after lactation. By measuring the ionized calcium levels of the blood directly cow side, the treatment can start sooner and is more effective. The new LAQUAtwin CA-11C has been specially developed for cow side measurement of ionized calcium in blood. Ionized calcium reflects more accurately the current calcemic blood situation compared to total blood calcium as it equals the free available calcium ions.

Power Quality Analyzer
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.
