A new density meter from Schmidt and haensch offering exceptional range, speed and accuracy in a compact instrument with extensive data aquisition and processing options. The instrument uses the oscillating U tube method to determine the density of the sample. This method relies on the accurate measurement of the frequency of oscillation of the sample in a U tube. The sample is excited electronically (piezo elecric) so as to make the liquid oscillate - the frequency of oscillation is directly related to the density of the liquid. The accuracy of the measurement depends on the instruments ability to compensate for the sample viscosity, to maintain a stable temperature and to correct for the compliance of various instrumental parameters. In other words the engineering precision of the unit. Schmidt & Haensch have applied their engineering experience in polarimetry and refractometry to produce a density meter with outstanding performance.

Modern - Digital - Ergonomic. Rugged reliable and easy to operate the TA9515  digital hot wire anemometer measures air flow in the range 0 to 4000 fpm. Ideal for grilles, diffusers, HVAC ducts, flow cabinets and similar applications.

The 2212 (formerly 2211) is self contained portable instrument for indoor air quality monitoring (IAQ) Ideal for inspectors, regulators, contractors and others concerned with occupational health and comfort. The instrument can used for making spot checks or more comprehensive studies over time using the data logging capabilities of the unit. The kit includes everything needed and is ready to use out of the box. The software allows for statistical analysis - average - maximum and minimum values and download to PC via an RS232 or USB connection.

pH - Automatic calibration with one up to three buffers out of eleven pre-program med pH buffers. Reads pH with 0.01 pH resolution.

Made in AmericaRoss chart recorders offer outstanding value and quality in compact bench top units. These instruments are made in the USA and come with a 2 year manufacturers warranty.

Features: Low Cost. 1/32 DIN ( 39.7 mm deep). 10.16 mm Red LED. Standard 3.5 digit. DC 5V non isolated / 5-24VDC isolated. 200mV - 200V measurement ranges. 1.999 mA - 2A measurement ranges. Replaces models AP202A and AP200.

Features: AC power supply 100 - 240V AC. DIN rail mounting. Input/Output/Power supply isolated. This terminal-integrated signal converter (isolator) isolates DC signals from other circuits and outputs signals of an amplified and integrated signal level. Rated input/output signals can be changed by changing the DIP switch setting. A slim case provides a body thickness of 12.5 mm. This unit works on AC power.

The Model OXY2 is an oxygen analyzer for monitoring the residual oxygen of purge and shield gases used in the welding of stainless steels. This unit has upgraded digital electronics and is an ideal replacement for the SGI2 and SGI3 instruments.
