Seismic Transducers Calibration System
-
Calibration of the seismic sensors should be conducted in the low-frequency domain, which means, that the relative method used for calibration of the vibration transducers is not applicable since it does not guarantee the required accuracy level. The problem is that the reference accelerometers have uneven AFR characteristic in the low-frequency domain. Thus, calibration of seismic transducers requires implementation of a different approach.

Humidity Indicators
-
A humidity detector, also referred to as a humidity meter or humidity gauge, is a device with a humidity sensor that measures the relative humidity in the air. PCE Instruments offers a number of humidity detector products including handheld humidity detector, data recording or data logging humidity detector, and combination or multifunction humidity detector devices that also measure parameters such as room or ambient temperature and atmospheric or barometric pressure. A humidity detector can measure relative humidity (RH) as a percentage (%) from 0 to 100 % RH, depending on the humidity measurement range of the specific model.Humidity is a key factor in everything from library and museum archival to agriculture, construction, manufacturing, transportation, warehousing, and heating, ventilation, air conditioning and refrigeration (HVACR). A relative humidity meter also is helpful in evaluating workers' heat stress risk on production floors and job sites. In addition, humidity plays an important role in the residential sector. If the humidity is too high in a private household, mold can grow. Mold creates a health hazard for anyone breathing the air in the home.

Sound Level Calibrator

-
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

Thermocouple Vacuum Gauge Tubes for Medium Vacuum
DV-6 Series
-
Teledyne Hastings, manufacturer of the original DV-4, DV-5, and DV-6 thermocouple vacuum gauge tubes, produces vacuum measurement equipment with exceptional stability, accuracy, and reliability under the most demanding conditions.The Teledyne Hastings’ DV-6 series thermocouple vacuum gauge tube acts as a localized sensor which is then paired with a selection of meters or controllers to provide reliable, cost-effective measurements in diverse applications. The robust sensor gauge tube is easily installed into vacuum systems and when properly excited, generates a thermoelectric voltage to provide a vacuum pressure measurement based on gas density. The DV-6 thermocouple vacuum gauge tube fully compensates for temperature and rate of temperature change.Thermocouple gauge tubes are calibrated on vacuum systems that contain N2 or Air, but can be used with other gases. Additionally, thermocouple gauges and their controllers can be recalibrated when a replacement thermocouple gauge tube is installed, following instructions in the manual. However, our DB-20 reference tube is available to confirm meter/controller performance. A complete line of installation accessories are also available to simplify the integration of our thermocouple gauge tubes into a variety of vacuum systems. Our goal is to provide “one less thing to worry about”, when performance matters! With a wide range of meter, fitting, relay and output options, the DV-6 series provides a reliable pressure measurement in numerous industries and applications.

The Keysight S960907B spectrum analyzer (SA) software application adds high-performance microwave spectrum analysis capabilities to the Keysight ENA-X up to 44 GHz. With fast stepped-FFT sweeps resulting from optimized data processing, the SA application provides quick spurious searches over broad frequency ranges. Conduct simultaneous spectrum measurements using test and reference receivers. For efficient measurements of spurious signals emanating from mixers and frequency converters, combine the multi-channel SA with the internal swept-signal generators. The SA application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy.
