Modutec PB Series Surface Mount Panel Meters

Modutec PB Series Surface Mount Panel Meters

Highlights:

The PB Series was designed to meet the expressed need of many customers for meters with a hard-hitting, big-dial area “industrial” look.

PB Series meters are available in many sizes, types, and ranges. Mounting stud configuration complies with ANSI standards: the number of studs is as follows: 1½” meters – 2 studs; 2½” & 3½” meters – 3 studs; 4½” meters – 4 studs. Meters in sizes 1½”, 2½”, and 3½” can be supplied in 4- stud versions at no extra cost.

AC meters in this series are offered in both d’Arsonval (rectifier type) and iron-vane versions. The latter has the virtue of greater standard accuracy and relative insensitivity to input distortion, while the rectifier type is less affected by frequency variations.

Model A800P Portable Tiltmeter

Model A800P Portable Tiltmeter

Highlights:

The Model 800P Portable Tiltmeter is a versatile and accurate hand-held instrument for monitoring structural and foundation movement. Measurements are taken from tilt plates that have been cemented or bolted to any horizontal or vertical surface. Indexing bars on the bottom and sides of the tiltmeter enable you to reposition it accurately on the tilt plate, every time. When continuous monitoring is not required, Model 800P is an excellent choice because only one tiltmeter is needed to make measurements at an unlimited number of points.

The Portable Tiltmeter System includes one tiltmeter, one power and display unit, and a tough plastic carrying case. Ceramic or Aluminum Tilt plates are purchased separately.
