MKS Instruments 1259B Mass Flow Controller PAIR — 100 SCCM N₂ — 0–5 VDCCONDITION

Used university lab surplus equipment in good overall condition. Both units are from the same MKS 1259B configuration and have matching specifications.

These units were removed from a laboratory/CVD system and retain their original MKS identification and calibration labels. Please review all photos carefully for cosmetic condition and exact configuration.

ABOUT THIS LISTING

This listing is for TWO MKS Instruments 1259B mass flow controllers with matching specifications.

Both units are marked:

MKS Instruments
Type: 1259B-00100RK-SP113/115-83
Flow Range: 100 SCCM N₂
Input: +15 VDC
Output: 0–5 VDC
Gas: Nitrogen (N₂)

The two units appear to be the same configuration and are being offered together as a matched pair.

SERIAL NUMBERS

Unit 1: 43708-1-1H
Unit 2: 43708-1-1I

CALIBRATION / IDENTIFICATION LABELS

Both controllers retain their original MKS/Coastal Instruments calibration tags and factory identification labels.

The calibration documentation visible on the units indicates configuration for N₂ (nitrogen) and a 100 SCCM flow range.

Because these are older surplus instruments, we are not representing the historical calibration stickers as a current calibration certificate. Buyers should evaluate the photos and specifications for their particular application.

TESTING

Both units have been inspected and photographed as shown.

We have verified the identifying labels, configuration, connectors, and overall physical condition. These are being sold as used surplus laboratory equipment rather than as newly calibrated instruments.

Please note: We do not have the complete original laboratory system available to perform a full process-flow calibration under controlled conditions.

WHAT IS INCLUDED

Two (2) MKS Instruments 1259B mass flow controllers
Unit 1: S/N 43708-1-1H
Unit 2: S/N 43708-1-1I

Only the two controllers shown are included.

IMPORTANT — PLEASE VERIFY YOUR APPLICATION

MKS mass flow controllers were manufactured in many different configurations. Please compare the exact model/type number, gas, flow range, input, output, and other specifications shown in the photographs with the requirements of your system before purchasing.
