JM Science (Grand Island, NY) has introduced a
titrator that includes free download software and
RS-232 cable to connect to the customer’s computer.
The AQUACOUNTER COM-300A Automatic Titrator
performs pH, acid/base, complexometric, redox, Karl
Fischer, photometric, non-aqueous titrations, and ISE (Ion-
Selective Electrode) measurements. Features include:
n The ability to determine TAN/TBN (total acid/total
base) in oils and P and M (relating to water hardness)
n One-touch calculations with a statistics package.
n Over 30 files of built-in method memory.
n The ability to store up to 50 results in memory or
download results to a laptop or desktop PC (download
n Balance and computer
n An optional volumetric
Karl Fischer Kit add-on.
Differential Pulse Generators
Saelig Company (Fairport, NY) has announced the
PicoSource PG900 Series Differential Pulse Generators
– high-speed, fast-transition instruments that can test
transmission paths with a fast pulse, instantly simulating
a wide-spectrum signal. The generators are suitable for
high-speed broadband measurements such as time-
domain reflectometry, semiconductor testing, gigabit port
testing, and radar systems. Features include:
n The ability to create pulses with less than 40 ps rise-
times for 200 mV pulses, or 60 ps for 2. 5 to 6 V
n Differential outputs with programmable de-skew in 1
n The ability for each of the outlets to function in single-
n The ability to simulate broad spectral signals driving a
50 Ω cable to a device under test.
n The reflected or transmitted pulse monitored and
displayed by a broadband or sampling oscilloscope.
n Two triggered step-generation technologies to suit
n Connection via USB to a PC running Microsoft
Spring-Loaded LVDT Linear Position
Macro Sensors (Pennsauken, NJ) has announced its
BBP Series of Air Extended, Spring-Loaded LVDT Position
Sensors. The position sensors feature a probe that moves
out and makes measurements only near the very end of
the probe movement when it is almost fully extended and
then retracts so the probe gets out of the way of damage.
n A 3/8” diameter.
n A repeatability of 0.000006” (0.15 µm).
n User-adjustable pre-travel.
n Reduced susceptibility to temperature changes.
n Positive stops, which prevent mechanical damage to the
probe from repeated overstroking.
n Rubber bellows covering the
n Availability in three standard
ranges: +0.040” (+1.0 mm),
+0.100” (+ 2. 5 mm), and
+0.200” (+ 5.0 mm).
Honeywell (Fort Mill, SC)
has announced that the
latest additions to its line of
feature highly sensitive sensor
integrated circuits (ICs). The
Standard Power Series – which includes four new sensor
ICs – offers a sensitivity of 11 Gauss max, making the
sensors among the most highly sensitive in their class for
standard power applications. Features include:
n A solid-state, non-contact, no-glass design.
n A supply voltage range from 3 to 24 VDC.
n Omnipolar operation.
n An operating temperature range from -40° to 185°F.
