PIN Diodes
-
The SemiGen SGP7000 series of PIN Diodes are processed with a high-resistivity epi that have intrinsic layers that range in thickness from 4 micron to 200 micron depending on performance specifications. These devices are typically manufactured with either a robust thermal-oxide passivation or ceramic glass for durable high-power applications. These diodes are made with a grown junction P++ layer that yields abrupt junction structures that provide low punch through voltages and minimize autodoping. They are available as chips or in your choice of packages.

PXI Isolated Millivolt Thermocouple Simulator - 8 Channel
41-761-004
Simulator
The use of two wire outputs and isolation from ground ensures that the 41-761 can be used to accurately simulate low voltages even in the presence of common mode voltages in the system. Each Vcold connection is independent permitting the 41-761 to be connected to multiple cold junctions.

pHTestr® 50 Waterproof Pocket pH Tester,
Premium 50 Series
-
The Oakton pHTestr 50 has a replaceable double junction sensor for longer life, an expanded number of applications, and easy maintenance. Double-junction electrode sensor handles wastewater and solutions containing sulfides, heavy metals, and TRIS. Electrode sensor offers a clog-resistant Kynar® junction and a recessed, glass pH bulb to protect against breakage. Valox sensor housing resists most chemicals. The keypad clicks to confirm operation, and allows access to a variety of functions. Calibrate up to three pH points with the auto-buffer recognition at both USA and NIST standard buffers. Additional features include an automatic temperature compensation (ATC), hold function, auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator.

Temperature Data Acquisition
THERMES-USB
-
Physitemp’s Thermes high accuracy data acquisition system has been redesigned to create a more versatile USB model. The new system requires no internal connections to your computer and simply connects via an external USB port on your laptop or desktop computer. Two versions of the data acquisition system are available. The standard version, THERMES USB, is connected to your computer USB port. The wireless version - THERMES USB WFI, can be either directly connected to a USB port or, with the included wireless receiver, positioned up to 100 feet from the host computer. Each unit will accommodate up to 7 type T thermocouple sensors and multiple Thermes units may be connected to the same computer for more thermocouple inputs. A high accuracy electronic cold junction compensation circuit maintains typical system accuracy of ±0.2°C over an ambient temperature range of 15 to 35°C. Individual offsets may be added to each input in software to facilitate individual calibration of each channel. (see THERMES-USB WFI)

Waveguide Faraday Isolators
-
RPG offers a series of fullband Faraday isolators. They cover the frequency range of 50 to 220 GHz. These isolators are Faraday rotation type ferrite devices with bandwidths covering a full waveguide band. They are compact and lightweight and provide much greater isolation than waveguide junction isolators.
