The EK-AEP series of internationally certified, intrinsically safe*1 balances is compact, lightweight and economical, bringing ease and security to anyone who needs to perform precise weight measurement in potentially explosive and hazardous environments.

The EK-AEP series is equipped with an optical connector from which it can output weighing results to a device in a distant safe area via optical fiber cable and an AD-1611 optical communication adapter.*2

• *1 Limits the energy available to a level insufficient to cause sparks or heat that can ignite flammable gases or vapors.
• *2 Both sold separately

Areas in which the EK-AEP series is certified for safe use

	Flammable gases/ vapors present continuously	Flammable gases/ vapors present intermittently	Flammable gases/ vapors present only accidentally
IECEx ATEX FM/FMc (NEC505)	Zone 0	Zone 1	Zone 2
FM/FMc (NEC500)	Division 1		Division 2

You can comfortably bring the balance to locations where ignitable concentrations of flammable gases, vapors or liquids are present continuously or for long periods of time under normal operating conditions (i.e. Zone 0 or Division 1).

• IECEx: Ex ia op is IIB T3 Ga
• ATEX: Ex II 1G Ex ia op is IIB T3 Ga
• FM/FMc (NEC505): Class I, Zone 0, AEx/Ex ia op is IIB T3
• FM/FMc (NEC500): IS / I / 1 / C,D / T3C+
• Tamb -25 to +40

Operation with off-the-shelf batteries*3 (life approx. 250 hours with backlight off)

This makes it unnecessary to secure power from a safe area via a safety barrier, allowing you to avoid the expense and inconvenience of special wiring installed by a qualified electrician. It also means that you can easily take and use the balance wherever needed.

*3 To be used only with four DURACELL AA alkaline MN1500 LR6, ENERGIZER AA E91 alkaline LR6 AM3, or Panasonic AA alkaline LR6 (XJ) 1.5V batteries.

Other useful features

• GMP/GLP compliant output to meet documentation requirements
• Auto power OFF function to save battery power
• Easy-to-read LCD display with backlight (16 mm character height)
• Hygienic and chemically resistant stainless steel (SUS304) weighing pan
• Multiple weighing units: g, oz, lb, ozt, ct, mom, dwt, gr, N, in addition to pcs (counting mode), % (percent mode) and SG (specific gravity)*6
• Comparator function for faster and more accurate filling, packing, sorting, etc.
• Response characteristics adjustable depending on the degree of drafts and vibrations at the location
• Security ring for wire-locking the balance to prevent theft

*6 Either tl (tael) or tol (tola) can be added upon request AD-1611 optical communication adapter for data output (sold separately)4

The AD-1611 receives optical data from the EK-AEP series and transmits electric signals to an external device such as a printer or PC through RS-232C or USB.*4
Three optical fiber cables of different lengths (10 m, 30 m, and 60 m) are available as accessories. You can select one that matches the distance between the balance and the AD-1611.

*4 The communication is unidirectional and the AD-1611 cannot transmit commands from the external device/PC to the EK-AEP series. The AD-1611 itself isnt explosion-protected.

When the AD-1611 is connected to a PC via USB,*5 the power is supplied from the PC and there is no need to use the AC adapter. (When the RS-232C is used, power needs to be supplied from the AC adapter.)
*5 Only a PC can be connected to the USB port of the AD-1611. A USB cable (type B male - type A male, 1 m) is provided as standard

more info AND Weighing EJ-12 Carrying Case for EJ Newton Scales - except for EJ-123 & EJ-303 more info Price: $67.50 In Stock Hard shell transport case for AND Weighing EKi, EWi and EJ digital scales. This hard cover carrying case features die cut foam that specifically designed for EKi, EWi and EJ digital scales. This carrying scale is convenient for carrying the digital scale or just storing your scale when not in use to lessen the chance of damage to the precision measurement weigh sensor. The EK & EJ Series scales incorporate a loadcell weighing sensor and whether the scale is turned On or Off if one applies an excessive load or shocks the platform you can permanently damage the scale. Damage to the loadcell is not covered under the manufacturers warranty and is considered abuse. This is for any brand or model digital scale. The optional EJ-12 carrying case can protect your investment and lessen the chance of loadcell damage especially if you transport your scale around a lot. more info AND AD-1611 Optical Communication Adapter more info Price: $422.30 In Stock Receives optical data from a balance/scale with an optical connector (e.g. EK-AEP series) and transmits electric signals to an external device such as a printer or PC through RS-232C or USB*1 Three optical fiber cable lengths (10 m, 30 m, and 60 m) available to match the distance between the balance/scale and the AD-1611 Requires no AC adapter for power supply when connected to a PC via USB*2 *1 The communication is unidirectional and the AD-1611 cannot transmit commands from the external device/PC to the balance/scale.
