## Overview

The Johnson Controls A-4000-120 Oil Indicator with Needle Valve is a precision instrument designed to detect and quantify aerosol-mist oil entrainment in compressed air systems. Operating within a 10 to 125 psig pressure range, it measures oil concentrations as low as 0.01 PPM with a flow rate of 2 scim/psig. Featuring a color-indicating cartridge and a conversion chart, it offers instant, reliable visual feedback to maintain optimal air quality and system performance.

## Description

The Oil Indicator detects aerosol-mist levels of oil entrainment that may be present in compressed air systems. Any oil present in the air causes a proportional color indication on a cartridge installed on the needle valve fitting. A conversion chart is included to determine the parts per million (PPM) value of the oil entrainment indicated on the cartridge.

## Features

- Line Pressure: 10 to 125 psig
- Measurement Flow: 2 scim/psig
- Lowest Concentration of Oil Entrainment Measured: 0.01 PPM
